1504 from LAX to IAH had a 5.5 hour maintenance delay. Saw it pushing back onto the taxiway while I was waiting for my flight, but then it returned on its own power to the gate 10 minutes later. Looks like they finally swapped aircraft and are on their way now. Anyone know what exactly was wrong with that bird?
I had something similar happen in February when my SFO-IAD flight got delayed by about 6 hours after numerous failed attempts to fix our 752. We ended up getting a p.s. bird which was quite the nice upgrade with the lie-flat seats.
