I ţravel with a friend from another state. Her flight is always listed... mine not.. so it doesn't help me alot for my itinerary as far as any airport changes. Also the deck of the ships i travel on have never shown up, but my friend can pull them up on hers. So, actually this app is of no use to me. Contacted the IT dept in regards to these issues n they told me they have never had the problem with 2 guests leaving from different airports so can't do anything about it. I don't use the app.
