Better organizing of entry and exit onto the plane regarding all of the baggage people haul on. There should be a better system so those with no baggage can get in and out more quickly. The baggage haul-on situation is absurd.

Better organizing of entry and exit onto the plane regarding all of the baggage people haul on. There should be a better system so those with no baggage can get in and out more quickly. The baggage haul-on situation is absurd.

The WIFI didn't work well enough to get through even 5 minutes of a movie I had selected (it just kept pausing and spinning), and I just gave up and read a book. The selection of movies was a little sparse though, so reading wasn't that bad of an option. This was an older 737-800, with undersized overhead bins -- but it doesn't make sense to me that we are told to slide our bags in with the wheels facing us (most people ignore that and put the handles facing us). This makes it more difficult to remove the bags (no handle). The flight went well, and the fruit/cheese platter I pre-ordered was good -- although it is a little annoying to have to pre-order for this (but I suppose it saves time). When I pre-order it automatically gets charged to my personal credit card (Alaska VISA), when I'd prefer to use my corporate card for that on business trips.

It was our baby’s first flight and everything went perfect. The flight attendant gave him his first set of wings and we were smooth flying from there.

This flight was significantly affected by poor wifi connections. I couldn’t get my work done because the wifi kept dropping. Even texts were not going through. There is no seat power in premium class either. I fly a lot. Today was my 10th flight in 4 weeks. This was by far the only flight that was sub par.

Good! Although I wish I didn’t have to check my bag at the gate, when I got on the plane there was plenty of room for the bag.

The cabin stewart took care of my garment bag and then made sure I did not forget it on my way out. The stewardess gave me water after I missed the earlier service (I was asleep). I received good service overall.

Everything was fine within the parameters of flying full aircraft. My only small regret was that the non-meal, "snack" type food options had 90% medium to high sodium items. They looked appetizing, but many, if not most older Americans are restricted in sodium intake, so maybe one low/no sodium option would entice people to buy them. I brought my own food. The staff, on-time and aircraft quality were great, as usual for Alaska.

Shorten up the country? All joking aside, it was fine. Thank you very much.

Horrible, missed my connecting flight because Alaska did not give me enough time

Flights were delayed for hours. Once boarded, we were left sitting on the tarmac for too long. I had to reschedule some flights despite scheduling over a 2 hr layover between flights. I ended up running thru the airport both times. I missed getting a meal at the airport and airline required pre-orders for meals so I was starved and exhausted when I finally arrived at my destination 6 hrs later than planned. I hope I don’t have to fly again soon. This was tortuous.
