i'll be over the moon if they bring the 21:00 LAX-IST flight back. It would let me get my full work day in SEA, and I could catch a 5PM flight down to LAX to connect to TK. This would be a huge improvement over what i currently do - redeye to JFK and then another redeye to IST.
Of course, it would be even more convenient if TK just launched SEA direct
