Booked on Flight 366 from Seatac to IAH. Continental delayed flight 366 because of 'weather' reasons for over 4 hours. Staff in Seattle and in Houston did none of the following: Did not post delay on their flight status webpage, did not send trip alert, did not offer alternative day scheduling, provided selective meal vouchers and then either denied that they were issued or claimed to have 'run out'. I saw and handled vouchers for flight 366.
From boarding gate to Executive Customer Service--the response was the same: blame the weather for poor service, near zero problem solving (could I fly a day later, could I fly and then drive, usual business travel routine re-routing practices. Flight landed at IAH with a 5 hour delay. As a final customer service--flight 366 was parked at one terminal while baggage went to another.
This flight (resarched while sitting in SEATAC for 5 hours) has a .4% on time record making it just possibly the worst flight on an airline who's on time record is not the best.
Bottom line: if you have to fly Seattle to Houston (IAH) pick a different carrier.
