- [Post-booking ancillary checkout](https://all-ancillaries-ey9upyybj-britoncos-projects.vercel.app/platform): Sell seats, bags, and extras after the booking is made. DepartCart adds a post-booking cart to your existing flow and writes each purchase back to the reservation.
- [The post-booking ancillary catalogue](https://all-ancillaries-ey9upyybj-britoncos-projects.vercel.app/platform/catalogue): Seats and bags are where a post-booking cart starts. The catalogue reaches across lounges, insurance, connectivity, ground transport, and cabin upgrades.
- [Extra bags after booking](https://all-ancillaries-ey9upyybj-britoncos-projects.vercel.app/platform/extra-bags): Sell extra checked bags after the booking is confirmed, priced as the airline filed them for that itinerary and added to the reservation automatically.
- [Three ways to integrate a post-booking cart](https://all-ancillaries-ey9upyybj-britoncos-projects.vercel.app/platform/integration-options): Tag manager, hosted page, or API. The three routes into a post-booking cart, what each one asks of your engineers, and how much control each one leaves you.
- [Priority support as a revenue line](https://all-ancillaries-ey9upyybj-britoncos-projects.vercel.app/platform/priority-support): Priority support turns a servicing desk from a cost centre into a revenue line, by selling the travellers who most want a human a faster route to one.
- [Refund protection on a non-refundable booking](https://all-ancillaries-ey9upyybj-britoncos-projects.vercel.app/platform/refund-protection): Refund protection makes a non-refundable booking refundable under defined circumstances, sold in the minutes after the traveller has paid a fare they cannot change.
- [Seat selection after booking](https://all-ancillaries-ey9upyybj-britoncos-projects.vercel.app/platform/seat-selection): 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.
- [Security, data handling, and compliance](https://all-ancillaries-ey9upyybj-britoncos-projects.vercel.app/platform/security-and-compliance): How DepartCart thinks about traveller data: hold as little as possible, keep card details with the payment provider, and put the detail in your agreement.
- [Post-booking ancillaries, by who you are](https://all-ancillaries-ey9upyybj-britoncos-projects.vercel.app/solutions): The post-booking gap looks different depending on whether you are an OTA, an agency, an airline, a tour operator, or a rail and cruise operator.
- [Airline ancillary merchandising](https://all-ancillaries-ey9upyybj-britoncos-projects.vercel.app/solutions/airlines): Your direct channel merchandises well and your indirect channel does not. A post-booking cart carries your own offer set and your own prices into both.
- [Ancillary revenue for OTAs](https://all-ancillaries-ey9upyybj-britoncos-projects.vercel.app/solutions/online-travel-agencies): You sell the flight, then the airline sells the seat and the bag. A post-booking cart on the page you already own keeps that revenue with the OTA.
- [Rail and cruise ancillary revenue](https://all-ancillaries-ey9upyybj-britoncos-projects.vercel.app/solutions/rail-and-cruise): The post-booking gap is not an air problem. On a rail or cruise booking the same window sits empty, and the extras that fit attach to the itinerary.
- [Tour operator ancillary revenue](https://all-ancillaries-ey9upyybj-britoncos-projects.vercel.app/solutions/tour-operators): A package is booked months ahead and touched several times before departure. Each of those moments is somewhere an extra fits, and today most of them sell nothing.
- [Ancillary revenue for travel agencies](https://all-ancillaries-ey9upyybj-britoncos-projects.vercel.app/solutions/travel-agencies): Adding a bag costs your agency an agent and a phone call, and earns nothing. Turn post-booking servicing into self-service, agent-assisted, and paid.
- [Supported Airlines and Aircraft](https://all-ancillaries-ey9upyybj-britoncos-projects.vercel.app/supported-airlines): Every airline, aircraft type and researched cabin layout covered by DepartCart seat maps.
