# Seat selection after booking Post-booking seat selection built on researched per-aircraft cabin layouts, so travellers see the real cabin, pick a seat that exists, and keep the sale. The seat map is the one part of a post-booking cart a traveller actually studies. They zoom in. They count rows back to the exit. They check whether the seat behind the bulkhead really has the legroom the label claims. And while they do it, they usually have a photograph of the same aircraft open in another tab. Post-booking seat selection lets a traveller choose a seat after the booking is confirmed, from a cabin map drawn for the aircraft actually flying that leg. Accuracy is what makes it convert: the traveller pays for a seat they can see, and the choice is written back to the booking automatically. ## Accuracy is not a detail of the product, it is the product A seat map that shows the wrong cabin does two expensive things at once. It costs you the sale, because a traveller who spots one wrong row stops trusting every other row on the page. Then it costs you again, because the traveller who paid anyway calls your support desk from the airport. Generic seat grids are where that goes wrong. One template stretched across an aircraft type cannot know that this operator flies nine abreast where another flies ten, that the exit row on this configuration is row 26 rather than row 30, or that the bassinet positions sit somewhere else entirely on the same airframe. Those are the rows travellers pay extra for, so those are the rows a map cannot afford to guess at. **Insight:** Every wrong row on a seat map is checked by someone. Travellers cross-reference seat maps obsessively, because a long-haul seat is the one part of the trip they still feel they control. ## What a researched layout actually records [Diagram: A researched cabin layout records the cabins on the aircraft, how many seats sit abreast, the pitch between rows, which rows are exit rows, which rows sit over the wing, and where bassinet positions are fitted. That is what lets a seat map show a traveller the real cabin rather than a generic grid.] What is recorded for a cabin, and what each fact changes on the map. A layout is not a picture. It is a set of facts about one operator's configuration of one aircraft type: which cabins are on board, how many seats sit abreast in each, the pitch between rows, which rows are exit rows, which rows sit over the wing, and where bassinet positions are fitted. Each of those facts is the difference between a seat a traveller will pay for and a seat they will complain about afterwards. ## How far the researched coverage reaches - **63** Airlines - **474** Researched cabin layouts - **49** Aircraft types - **39** Countries Underneath those layouts sits the seat-level detail that decides whether a map is worth showing at all. - **114,182** Mapped seats - **1,029** Cabins - **265** Exit rows - **438** Bassinet rows Two of those numbers are worth dividing into each other, by way of illustration. 114,182 seats across 1,029 cabins averages roughly 111 seats a cabin, and that is the scale of the thing a generic grid is quietly pretending to approximate. Seat pitch is recorded for 606 of 617 cabins, and the eleven gaps are known gaps rather than invented figures. The full list is public. Every airline, aircraft type, and layout is on [the supported airlines page](/supported-airlines), so you can check your own busiest routes before you talk to us rather than after. ## What the traveller does 1. **They open the page you already send them to** The confirmation page, the manage-booking page, or an email link back into your own flow. No new account, no re-entry of the itinerary, and nothing that feels like starting again. 2. **They see their own aircraft** The map is drawn for the aircraft scheduled for that leg, with the cabins, the exit rows, and the bassinet positions where they really are. Seats the traveller cannot take are shown as unavailable rather than quietly left off. 3. **They choose for everyone on the booking** One pass through the map covers every passenger and every leg, which is the difference between a family finishing the task and abandoning it halfway. 4. **They pay once** A single payment covers everything in the cart, in the currency you already sell in. ## What happens after payment The seat is written back to the reservation automatically. That sentence is short because the outcome is short: nobody on your team touches it, no backlog of manual work forms behind the revenue, and the traveller sees the seat reflected in their booking rather than waiting to find out whether it worked. That last point decides whether they buy anything else from you. A traveller who has just watched a post-booking purchase land correctly is a traveller who will [add a bag](/platform/extra-bags) a fortnight later. ## Check your own routes against the coverage Bring the ten aircraft types you fly most and we will show you the layouts behind them.

They are researched per aircraft type and per operator rather than generated from a generic template, then checked against what the airline returns for the specific itinerary. The public coverage list at /supported-airlines shows every airline, aircraft type, and layout currently mapped. ### What happens if the airline changes the aircraft after the traveller has paid? An equipment change is a normal part of airline operations, and the seat the traveller holds is reconciled by the airline in the same way it would be for a seat bought on the airline's own site. Your team is not left to work out what happened from a spreadsheet. ### Does an agent have to do anything once a seat is sold? No. The seat is written back to the reservation automatically, so no manual work builds up behind the revenue and the traveller sees the seat reflected in their booking. ### Which bookings can carry a post-booking seat sale? Bookings held in Sabre, with seat content sourced through both ATPCO filed content and NDC. The map is requested for the itinerary in front of the traveller rather than read from a stored table. ### Can we style the seat map to match our brand? Yes. The map is presented inside your own colours and typography, and how much control you take depends on whether you run it through your tag manager, as a hosted page, or through the API.
