The American Airlines AAirmail e-mail newsletter for frequent fliers says this morning that
"American Airlines schedules and fares are again being displayed on Kayak.com and SideStep.com. You can now find our content through these meta-search engines for purchase on our award-winning web site, AA.com."
This brings to an end a spat between American and Kayak (which owns Sidestep, too.)
The Cranky Flier has more details.
Kayak now displays fares for all major airlines except for Southwest (which you can only find at Southwest.com).
