OrderChange - Useful Information
- Both free seats and paid seats can be booked in a single OrderChangeRQ
- Payment section need not be provided if only reserving free seats
- EMD will be issued for every paid seat reserved i.e one EMD per paid seat will be issued
- Error will be returned if seat purchase is for a single flight segment and at least one requested seat can't be booked e.g. 3 Pax requesting to book seats and one seat is not available for some reason
- Warning message will be returned if seat purchase is requested for more than one flight segments and for some reason seats cant be booked on at least one flight segment
- Warning message will be returned with the seat amount that was charged when seats are not booked for all flight segments e.g. Flight 1 - £25 for seat 41A, Flight 2 - £25 for seat 41B so in OrderChangeRQ seller would pass £50, but for some reason if we booked seats only on Flight 1 then a warning message will be returned with the correct amount that was charged
