Just a quick note to thank LuizMiranda for sharing his flight tracker tool. Using the track fares feature, I was able to catch a change in availability that allowed me to switch from a PDX-SEA-SFO-PVR routing to PDX-SEA-PVR, travelling on the same flight with friends, and getting me an extra hour in the sun!

Now, I can use the upgrade tracking feature to see if a U seat opens up, so I can call and snatch it up with my companion certificates.

Much easier than checking the AS website everyday! Thanks LuizMiranda
