We sat on the tarmac for 25 minutes after landing and it caused me to miss a connecting flight. It turned a 7 hour travel day into a 14 hour travel day. That really sucked.

We sat on the tarmac for 25 minutes after landing and it caused me to miss a connecting flight. It turned a 7 hour travel day into a 14 hour travel day. That really sucked.

Alaska is usually amazing. This time was the exception. Something in the plane broke and had to be fixed. It happens, I get it. So instead of arriving home at 1030pm...I arrived at 3am. Needless to say it was a looooong night. Especially when I got to the airport at 430p for a 645 flight.

If the flight from Seattle to Eugene hadn’t been delayed for mechanical reasons we never would have made it. 45 minutes is not enough time to deplane and get clear across a big airport like SeaTac.

perfect flight!! couldn't have been better unless it was free!

the planes were beautiful!! crew was outstanding...flight on time and baggage was quick... can't think of ANYTHING that could have been better. thanks for a great trip!!

This was a smooth ride all the way with plenty of space in main cabin for my 6 foot frame over 5.5 hours. The stewards were pleasant and attentive. We bought the tapas box which proved to adequate for us on this flight. It was pretty hard to find restaurant food to go that is vegan for us in Kona Airport so buying this helped lots.

My wife and I had seats next to each other, but when our boarding passes were printed, British Airways had moved me away from her and refused to fix it. We tried to fix it at the boarding gate and were just told flatly "no". Never again.

Great, but their check-in sinage is not clear and wastes folks' time.

One the nicest and great air crews I’ve experienced and I’ve flown a lot

3hrs. delay in New Orleans....missed my flight in Seattle by around 5 minutes....same airline. Not sure why they couldn't have communicated. And after talking to the flight attendant on the first flight, they said about 20 passengers are running behind but they still didn't make an announcement to let connecting passengers get off the plane first. So here we were waiting on others to get off the plane that most likely had little to no 'time-crunch'
