Airline Upgrade Policies for Alaska, American, Delta and United

Scott Mackenzie has written a ‘compare and contrast’ post about the upgrade policies of Alaska, American, Delta and United Airlines.

Summarizing Differences between Airline Upgrade Policies

This is a complex topic, since policies vary for full-fare, discounted and award tickets, and between the various elite status levels that each airline’s frequent-flier program offers. Also, can you upgrade with FF miles? And finally, can your companion upgrade if you do?

This is a good reference, kudos to Scott for preparing it!
