Hi Susan, Generally speaking, you'll never get every possible route returned with a search as, especially when you're talking about all airlines in an alliance, there are just too many possibilities and the reservation system only returns so many flights in a search (and we show all that are returned). You can narrow down the possibilities by specifying a connecting city or clicking the "Don't Show Interline Connections" option. Or specifying a few airlines instead of an entire alliance if you know you want to see a specific airlines flights. Also adjusting the time of day of the departure or return date will help to narrow down a large list of options.
It would be helpful if we knew the specific searches with dates that you were looking at and the specific flights you think you should be seeing. Please send an email to
