For me it was bad, bad, bad ... then good, good, good .
AA canceled the MIA-DFW 777 yesterday, so everything was oversold and F cabins were completely booked (no upgrades). I was put on the MIA-LAX 757 flight, in row 10 (at least) ... Was not able to sleep. My final destination was SAN . Good thing AE oversold flights to SAN and was able to score VDB Vouchers for future travel.
