In preparation for the recent American Airlines/US Airways merger, we needed a seamless way for travelers to select and purchase upgraded seat options on US Airways flights while booking travel on aa.com.
Overall, the biggest challenge was that the two companies had the same names for different seat options. A 'Preferred Seat' for American is a paid upgrade while a 'Preferred' seat for US Airways is offered free to elite members. The dynamic legend separates these product names for users counteracting any confusion.
Included are mobile and desktop wireframes for the elite seatmap and dynamic legend.
