No mechanicals no delays. I’m happy
The flight attendents were great....first class.
Best airline at the moment
Alaska was good. But Orbitz not so good. When I checked in online. It showed no other available seats and we had bad seats. Yet when we got on board there were multiple open rows of seats. We also were in the last boarding group and near the back of the plane. Makes me think Orbitz doesn't have any buying power with the airline. So I will have to consider using Orbitz again in the future.
Wish we’d been served something to eat besides pretzels
Thanks for making my holiday travel easy and for Being reliable
WiFi really is so awful in all three Delta flights I took this month. It is worthless really. I do appreciate the free movies but on two of the flights the monitors didn’t work the entire flights.
Seats were very close together. Knees touched seat in front for the man next to me.
Not at this time.
although I purchased my ticket weeks in advance, they overbook to an extreme and tried to bump me. They wouldn't explain or help me. I was left standing alone in the terminal after everyone else had boarded scared that I wouldn't get my flight to see my dying aunt. Staff was really uncaring! Both flights were delayed. I will NEVER fly Alaska Air again.
They had us board the plane, knowing the first officer wasn't even at the airport yet, and they had no ground crew, so we sat for almost 2 hours in the plain waiting. And then after all that, they didn't even have a damn snack. We got treated like crap and they couldn't care less about the large delay
Delayed sat on plane for 1.5 hrs
Learn to update boarding passes last minute of the name issue incorrect by two letters and the airline is willingly to work with you
We waited one and a half hours to leave Seattle and had to pay for soda etc on the phone. They did nothing nice for us due to huge delay.
Level of service for the money was sadly lacking
They canceled our fight in Denver, left us no options. I had to rent a car in Denver and drive to Bismarck North Dakota
I will never fly frontier again.
Have to call delta customer service for refund of my paid upgrade because section was overbooked even though purchased at checkin 23.5 hrs before flight AND then flight was 2 hrs longer because diverted to other city for plane fuel. Disappointed with delta.
