Airline reviews

The seats are too small/crowded. It is frustrating to be forced to sit with someone who is overweight as they crown the other seat. Nothing against the person…just the airline companies who continue(over decades!)to reduce seat sizes. Americans are fat. Those of us who are not are tired of being compromised by the airline companies who don’t faces that fact and make adjustments. Maybe have “overweight seats”? Maybe give us a discount for being forced into an uncomfortable flight due to others overweightness? Please, make adjustments…be accountable. Thanks!

Good flight overall. Lots of bumps during flight but pilot kept searching for smooth air

We tried for days to use online Alaska Airline app we needed to know what Gate to depart from . When we got there we were given a paper boarding ticket with the wrong gate on it . We almost missed this flight . It caused great stress and caused a health side effect. The previous flights April 24 started hour late mechanical issues . We were not allowed to depart plane in time to get correct gate and missed our flight .

Couldn’t order food for the family because all the good food was unavailable. We opted for bringing something on with us. I also didn’t like that I had to have T-mobile for online movies. Stupid.

The crew was great and everything went smoothly coming and going.

Had to buy a snack box as I am gluten free. They should be free in extra comfort. Food they provided was awful. Not enough water stops.

You can standby to get on earlier flight if the seat is open.

it was good except the too big men in my personal space.

Free WiFi was awesome. I hate the five hour delayed take off.. arrrgh!

I wasn’t aware that we needed to supply our own screens for entertainment
