It drives me crazy when I read drivel like this:
There are, however, a couple of notable exceptions. Discounters Southwest and JetBlue simply can't offer elite-security queues. To do so would violate their iconoclastic, single-class operating philosophies.
"All of our passengers are elite," says Southwest spokesman Ed Stewart.
Some facts:
1) Southwest placed in the top 5 for "elite program of the year" in the Freddies this past year; the main benefit is the Companion Pass
2) At PDX, members of Southwest's FF program can use the elite line, while non-members cannot
3) Passengers who buy full-fare tickets are allowed to fly standby, while those who do not are not allowed
Need I go on? There's nothing "single-class" about Southwest except the cabin itself.
