I've asked to use a Southwest drink coupon on Airtran flights without luck. The Airtran flight attendants seem to enjoy telling me that they're not Southwest. I remind them that your new CEO, Gary, says you're one big happy family. This shouldn't be so difficult. Can't someone solve this so I can have a free drink when I'm stuck in my pre-assigned middle seat? As A-list Preferred, I'm not enjoying this. Solving a few of these little problems like cross-company drink coupon usage and a better seat assignment algorythm might provide a little customer delight. Does anyone care?
