What you get

Four things a booking engine will not do for you

None of this is exotic. It is ordinary airline distribution work that consumer websites are not built to perform, because performing it requires a person who can read a filed fare rule and talk to the carrier.

Three pricing paths, compared out loud

Your itinerary is priced against the airline’s published fare and against the carrier’s own branded fare families, so you hear what each option costs you in rules as well as in money.

The fare rules read back before payment

Changeable or not, refundable or not, checked bag included or not, seat assignment free or paid, upgrade eligible or not. Stated verbally, then repeated in writing on your confirmation.

Someone who stays on the file

Schedule change at 2am, a cancelled inbound, a waiver that has to be requested by a travel agent rather than a passenger — the same desk that ticketed the booking works it.

Fees named and published

Where we charge a service fee it is quoted before we act and listed in a public schedule. Airline penalties are shown as the airline’s, never bundled into ours.

Fare families

What is actually included at each fare level

The same seat, four different contracts. Each fare family is a separate filing with its own rules on changes, refunds, baggage and seat selection, so what is included is decided by the filing and not by the cabin — the shape below is the common structure on US and transatlantic carriers, and the rule attached to your specific fare is what an advisor reads to you line by line before you buy.

Typical branded fare inclusions. Indicative only — confirm against the specific fare rule for your flight.

Basic economy is not a trap — it is a perfectly rational purchase if you are travelling with a backpack on fixed dates. It becomes expensive the moment your plans move. Our advisors will tell you the dollar gap between basic and standard on your specific flight so you can price the flexibility rather than guess at it.

How a flight quote is built

An airfare is not a price the airline decides once. It is the output of a fare construction: a base fare filed in a specific booking class for a specific origin and destination, plus government taxes and airport charges, plus carrier-imposed surcharges, all assembled against a set of rules that dictate what you may and may not do afterwards. When your search reaches the desk, an advisor rebuilds that construction three different ways and compares them.

The first path is the airline's published fare, the one filed through the industry fare-filing system and visible to every agency and to the carrier's own website. The second is negotiated and consolidator inventory: net fares an airline releases through agency channels under contract terms that forbid publishing the price on a web page, which is why they can only be read out to you rather than listed. The third is the carrier's branded fare families accessed directly, which sometimes bundle a checked bag or a seat assignment at a lower total than buying the same items separately.

Those three numbers are rarely the same, and the cheapest one is not automatically the right one. A negotiated fare that saves eighty dollars but cannot be changed at all is a bad purchase for a traveller whose meeting date is still moving. That trade-off is the conversation, and it is the reason the quote is spoken rather than displayed.

Published, negotiated and why some fares are phone-only

A negotiated fare exists because an airline wants volume on a route and is prepared to discount it away from the public market. The contract that creates the discount almost always contains a no-online-display clause: the agency may sell the fare, but may not advertise the price. That single clause is why a phone number sits at the top of this page and why a search box alone cannot show you everything.

Negotiated fares carry their own conditions and they are frequently tighter than the published equivalent. Common restrictions include no voluntary changes, no refunds beyond the taxes, no upgrade eligibility, reduced or zero mileage accrual, and a prohibition on the airline reissuing the ticket directly — meaning that if something goes wrong, the ticket has to come back to the issuing agency to be touched. We explain that constraint before you buy it, because it changes who you call at 3am.

There is a wider point here that we would rather state than let you discover. On short, competitive domestic routes flown by a single carrier, the published online fare very often wins outright, and the honest advice is to book it on the airline's own site so you sit in a direct relationship with them. Our value shows up on long-haul, multi-carrier, multi-city and premium-cabin itineraries, and on anything that has already gone wrong.

Routing, connections and the risk you cannot see in a price

Two itineraries at the same price are not the same product. The variables that matter are whether the flights are on one ticket or two, the connection time relative to the airport's published minimum connection time, whether a connection crosses a terminal or a border, and whether the carriers involved have an interline or codeshare relationship.

On one ticket, a missed connection is the airline's problem: they are obliged to rebook you under their contract of carriage, and your bags are checked through. On two separate tickets bought independently, a missed connection is entirely your problem, your bags stop at the first ticket's final destination, and you buy a new ticket at the walk-up price. Booking engines that stitch together separate tickets are legally entitled to do so and often do not make the distinction loudly. Our advisors will not build you a self-transfer without saying the words out loud.

The same applies to connection length. A 45-minute connection that technically meets the airport's minimum is legal but fragile, particularly through a hub that is weather-exposed or where you must clear immigration and re-check bags. If you are connecting to a cruise, a wedding or a rental counter that closes for the night, we will build in the buffer and tell you what it costs.

When you should not call us

If you are flying a simple non-stop domestic round-trip on a single carrier within the next few weeks, on dates that will not move, and you hold status or a co-branded card with that airline, book direct. You will keep the cleanest possible relationship with the operating carrier, and the fare is very unlikely to be beaten. Calling us to save nothing wastes your afternoon and ours.

Equally, if you are shopping purely on headline price and are willing to accept any routing, any connection and any fare rule, a metasearch engine will get you there faster. We are not a cheaper version of the internet. We are a different service: one where a named person carries the file, sees the rules, and can be reached when the schedule changes.

After the ticket is issued

Ticketing is the moment your reservation becomes a financial instrument. Before it, you have a booking record — a PNR — that holds seats but does not guarantee price. After it, you hold an electronic ticket number, and the fare rules attached to that ticket govern everything that follows.

Most tickets originating in the United States carry a 24-hour risk-free cancellation window, provided the booking was made at least seven days before departure. Beyond that window, what you may do depends on the fare: standard economy on most US carriers no longer carries a domestic change fee, though you still pay any fare difference; basic economy is normally excluded from that concession entirely. If the airline changes or cancels on you, a different and much stronger set of rights applies, including a refund entitlement to the original form of payment when a flight is cancelled or significantly changed and you decline the alternative offered.

We keep the file. Adding a frequent flyer number, requesting a wheelchair, correcting a middle name to match a passport, chasing a schedule-change waiver, converting a ticket to a credit and later reissuing it — all of that is ordinary post-ticketing work and it goes to the same number. Where a service charge applies for that work it is published in our fee schedule, and refunds follow our refund and cancellation policy. If you want the mechanics in detail, start with flight reservations, then changes and cancellations.

Answers

Flight booking questions worth asking before you pay

Answered against the rules that actually govern the booking — the carrier's filed fare, the rental agreement, the regulation — rather than from general advice.

Does Zeptotravel operate flights?

No. Zeptotravel is a travel agency and booking intermediary, operated by zeptotravel llc. We hold and issue tickets on airline stock through the global distribution systems and through direct airline connections, but the flight itself is operated by the carrier and governed by that carrier's contract of carriage. Anything the airline is obliged to do for you — reaccommodation, involuntary refunds, baggage liability — is owed by the airline, and our job is to press the claim on your behalf.

Why would I call instead of booking on an airline website?

Three reasons, and only three. First, unpublished and consolidator fares carry contractual clauses that forbid public display, so they exist only over the phone. Second, complex routings — open jaw, multi-city, mixed carrier, stopovers longer than 24 hours — are frequently mispriced or refused by consumer booking engines but price normally through a fare-construction desk. Third, anything abnormal: a waiver request, a name correction, a medical case, a group of ten or more. For a simple non-stop domestic round-trip on a single carrier, booking direct is often the cleanest route and we will say so.

What is a fare family and why does it change the price so much?

Airlines file several branded fare products against the same seat. The seat is identical; the rules are not. A basic economy fare and a standard economy fare on the same flight can differ by a hundred dollars or more, and the difference is entirely in seat assignment, baggage, changeability, refundability, upgrade eligibility and mileage accrual. The comparison table above sets out the usual pattern. We read the specific rules of the fare you are buying before you authorise payment.

Is the price on my quote the price I pay?

Yes. We quote the total payable amount — base fare, government taxes, carrier-imposed surcharges and any Zeptotravel service fee — as one figure, in line with US DOT full-fare advertising requirements. Ancillaries you choose to add later (checked bags, seat assignments, upgrades) are separate and are priced by the airline. Our published charges are in the service fee schedule, and how quoted prices can move before ticketing is explained in price accuracy and fare rules.

How quickly is my ticket issued?

Most bookings are ticketed within minutes of payment clearing. A reservation is created first (that is your PNR), then the ticket is issued against it and an electronic ticket number is generated. Until that ticket number exists you have a reservation, not a ticket. Consolidator and negotiated fares occasionally sit in a ticketing queue for a few hours; if that applies to your booking we tell you at the time and confirm by email when the ticket is issued. See flight reservations for the detail.

Can I hold a fare without paying?

Sometimes, and it depends entirely on the carrier and the fare. Some airlines file a genuine hold product; some allow a ticket time limit of a few hours on a booked-but-unticketed PNR; many low-cost carriers allow neither. What almost always exists on tickets originating in the United States is the 24-hour risk-free cancellation window under US DOT rules, which is a different mechanism — you pay, then you may cancel for a full refund within 24 hours if you booked at least seven days before departure.

Do you charge a fee for changes and cancellations after ticketing?

Where a service fee applies it is published in advance in our post-ticketing service fee schedule and quoted to you before we touch the booking. It is separate from, and always identified separately from, any airline penalty or fare difference. Our refund and cancellation policy explains which charge belongs to whom.

Can you book the car on the same file as the flight?

Yes, and there is a practical reason to. When the flight and the vehicle sit on one file, an advisor can see that a schedule change has pushed your arrival past the rental counter's closing time — and move the pick-up before the counter shuts rather than after you land to find it dark. Start with car rental, or ask the advisor who prices your flight.
