One World Alliance has been the mainstay of my frequent flyer follies. I've flown AA, BA, Finnair, and Malev regularly and an occasion stint on JAL and Iberia. It just makes the trip that much easier when you can track your business. Not all the players have apps but AA has been keeping us connected online for a while. They offer mobile bookings, check in, boarding passes, terminal maps & AAdvantage info. So with over 700K AA miles to date, I chose AA for this list. Now if only they were my favorite airline. That's another review.
