I've spent around $10,000 on flights out to San Jose this year on Delta. In November, AirTran flies into SFO. Let's see . . . fly on Delta on more expensive fares when I'm out of upgrades? Or I could use our corporate account at AirTran and get unlimited FREE upgrades from coach fares at time of booking for more expensive fares.
Sure, Delta may match but it's AirTran that sets the price bar and absolutely deserves the business.
