The messaging about the change in flight destination and options for getting to SFO was poor. There should have been frequent updates. When I spoke to the boarding agent moment before we were supposed to board, he was flippant and offered no help before the announcement was made that transportation would be arranged. It was as poor of an experience that I've ever had.

When I spoke to the boarding agent moment before we were supposed to board, he was flippant and offered no help before the announcement was made that transportation would be arranged.

My plane ride down landed 20 min late. Boarding at SFO was strange too. The people at the terminal were nice—but, boarding lacked direction, and was confusing . Coming back was worse—the plane was hours behind—and I barely caught the last Bart train back to San Francisco (3 min more and I would have been in trouble). It was a very stressful trip, and it didn’t need to be.

dont re-route to San Jose. Re-route to closer airport. Provide shuttle bus to go to SFO, not just LYFT vouchers.

WiFi connection bad. Food is really awful. Crew very nice and efficient

It was the worst experience because they delayed the flight by 2 and half hours. We were supposed to depart by 3:41 but they did the depart by 6 pm. It was so boring!!

This was a short flight with many open seats. Overhead space is limited and there are no screens in the seat back. But overall the flight was comfortable and fast.

Poor experience. 4 hour delay. 2 hours because of weather and runway construction at SFO. But gate logistics were a mess (gate was used by an unsigned flight to SAN first (!) ... lots of time spent weight balancing the flight because of an inoperable baggage hold (initial loading should have taken that into account, since plane had been flying that way that day) ... and then plane had to go back to gate for more fuel because of SFO delays (easily could have been done - and foreseen - while reweighting the plane). Airline came across as extremely disorganized. Note: on-board experience was fine ...

I think in 6:15 hrs flight the airlines should give some meal and not just couple of cookies People reach their homes at around 12 mid night and then they have to make dinner and eat I started my home at around 5 o clock and no food till 12 midnight You should give some reasonable meal in flight Thanks

The only options for beverages were water and apple juice. When did that happen?

Pretty terrible. The aisles on this flight were too narrow so we had to carry our baby, care seat, luggage, travel stroller step by step down the aisle slowing down a lot of passengers in the process. Not only was this a safety hazard but remember that scene from game of thrones where Cersei walks naked through the streets? It felt about as excruciating as that except both me and my husband were carrying 50lbs of weight while everyone from the flight attendants and passengers dolled out comments like “that stroller doesn’t fit in the overhead compartment and you should check it at the gate” when it is a travel stroller that absolutely fits and did fit in the overhead compartment. The flight said it was 30 min delayed but in actuality we did not take off until 1.5 hours past the original time. It was absolutely terrible. Alaska also charged us 200 dollars just in baggage fees even tho we took the time to buy two check on baggages via their app and bought an extra seat for our child and they still refused to overlook our first time flying with them. Everyone in general looked super miserable and traveling with them with a child is pretty much untenable. Lastly I originally thought I had booked an AM flight for my family but it was a PM flight which I knew was not going to end well since we had a 1.5 year old with us on a flight that gets in 9p. I ended up calling Alaska to try to change the first leg for a change fee, and would even have accepted half of a refund to book a completely different flight but of course they refused and absolutely allowed no flexibility to plans so I guess my revenge was our baby cried for 3 out of the four hour flight and hopefully convinced every miserable person on that flight to never fly Alaska again 🤷🏻‍♀️

The net issue I had was with the gate agent. We had added a carryon to our boarding pass when we checked bags. When I got to the boarding gate the agent was rude asking why I had a backpack - I said I added it - even had an orange tag on it. She ripped my tag off and swung her monitor around to show me how she was right- saying it isn’t wasn’t listed - only a checked bag. I explained again that I wasn’t sure what the issue was but I wouldn’t have an orange tag if I hadn’t added it. Then she finally checked my husband’s boarding pass and found that the agent at checkin had added my carryon to his boarding pass instead of mine. She sent me on my way without my orange tag. Was a bit embarrassing for me the tone she used with me assuming I was trying to get away with something.

Gate agent asked if I could switch seats so a family could sit together. Agent moved me to a seat in the front of the plane, no charge. It was easy. The agent did a great job.

Great seat space. However food and drink prices outrageous. Jabbing to pay for a carry on bag or stuck paying at the gate too much.

Every Allegiant Air flight I've ever taken has been delayed. This flight was delayed a full 2 hours. It was excuse after excuse after excuse. It was a flight from southern Florida. They made us board the plane on time, but made us wait for 2 hours on the tarmac. Because the engines were kept shut off, so was the air conditioning. One can only imagine how hot the air was in the cabin over those 2 hours on the tarmac, while in the hot Florida sun. Just terrible.

Actually, for the price, I'm willing to put up with a little discomfort (upright chairs) and at times inconveniences (like any airline), lack of entertainment (I can bring my own). My flight was non stop and smooth. I would fly this route again.

The flight was delayed 6 hours and we were only offered an $8 food credit. My husband stood in line to get the credit for 45 minutes and when he got close to the end of the line the computers went down.

Worst ever! Flight cancelled supposedly for weather even though we k ow of many others who flew into Bangor same time no problem. At the airport there was no customer service at all just refund and no possibility of rebook for 3-4 days. Aweful won’t fly with them again!!

It’s a budget airline so adjust expectations accordingly. Nothing is without a fee but such is necessary for tickets to remain so affordable.

No complaints. It’s a budget airline so can’t expect any frills.

My TSA number was missing from my ticket which shouldn’t have happened since it’s in my file. The on board flight attendant who was a male, did not want to help me put my luggage in the overhead bin and made a very rude comment and was very unpleasant. The good… the woman who fixed my ticket with the TSA number was excellent and I had extra legroom which was perfect.
