Airline reviews

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.

This leg was better than the previous leg mostly because I upgraded my searing and the crew was nicer

I was not given a seat when I bought the ticket. I know airlines are trying to squeeze every penny out ot the customer, but we are buying a seat on the airplane, right? I find this irritating with all airlines, but especially Alaska because I fly it so often. No sense of customer use and loyalty.

I’m a first time mom and traveled with my 18mo old boy and it was not a great experience with the flight attendants. They were not friendly or helpful at all. It’s hard enough traveling with a toddler and have people be rude and unkind does not help.

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.

only refreshments and biscuits available but it was a short flight from LAX to LAS thus it was fine.

High travel time and the flight was full but the staff handled it all well.

The person sitting next to me did not fit in one seat, so I effectively only had half a seat to myself. Airlines should come up with a strategy to sit oversized people in a way whereby they are comfortable but don't disrupt or take over other people's seats. It's unfair.

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

This was a quick flight so more like a shuttle and everything went well. There was no food or beverage.

I didn’t not like that I could not select my seat and ended up with the worse seat.

Great, on time departure, friendly and accommodating crew, great leg room, Smith flight

Honestly, I didn’t expect that I will experience this long time wait during the check in. There was only one person who was taking care of the passengers for the economy class and it took us to wait about one hour to do our check i. As a result we barely get to the airplane as the gate was at the end of the airport. That is totally not professional where one crue is working at the registration desk with economy and 3-4 crues are helping for the business class.

I guess they don’t serve drinks on planes anymore

Delta planes have the WORST seat comfort of any plane in history. It's the opposite of ergonomic, in every sense. They also recline minimally, are covered in a vinyl and have no feet rests. Then the disembarking process is chaotic and time consuming (because of the way they load the plane and deal with luggage). Overall, somewhat frustrating but we arrived safely :)

It was a very smooth ride. Not sure on a flight departing at midnight can be much better but it was late arriving and I had an early day so really just the logistics.

Really liked the choice of the 4 free snack options. Crew great. Good vibe on plane.

Very disappointed in the food selection. It was not good compared to other airlines.

Good breakfast granola bar good crew seamless flight and baggage transfer we’ll done!

Everything was great but the difference in paying for comfort + did not seem worth it.

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.

Left 2 hours later for delayed I had to take care a kid with special need since people don’t want to move to accommodate the rest of the family. . It wasn’t bad but that made me upset that people can be that selfish.

For a 22 minute flight all you expect is for it to be safe and comfortable

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

No snacks served! Seating in the kast row in uncomfortable.

Wouldn’t let me check in said couldn’t find a ticket had to wait very long Time

I liked that we arrived earlier, you could improve your snacks give away

Flight was fine, it was delayed but only 30 minutes, staff were efficient, lady making announcements at LAX was really hard to understand but the rest were great.

I really enjoyed the staff and crew! Very positive and happy people! Made the experience easier! The entertainment was a bit lack luster. Better movie options as well as equipment that works smoother could be nice. My ear buds from the airline didn’t work and my tv screen had a terrible delay that made it hard to search for things to watch. Also the selections were very limited.

Flight was diverted to Canberra because Not enough fuel to circle on Sydney’s skies waiting for showers to pass. After that everything went wrong. It took forever to put fuel. Once back rolling, we stopped short of takeoff because crew had reached maximum work hours per shift. Back to gate we waited and waited in the plane with no water and no food - a total of 4 hours. Received contrasting news about the follow up of our trip. Finally we disembarked but our luggage could not be processed there as not enough custom agents. We ended up on buses and arrived at Sydney airports after a 3 hours trip. There we had to queue in line with 240 more passengers to file a lost luggage claim. We received the luggage after 48 hours, many of which spent holding with non-existent United customer service. Never able to speak to an actual person during those long phone calls. Finally on a chatline I could talk to a baggage agent, who filed another report as our luggage did not appear anywhere in their system. Thus it was surprising to get it back.

I got upgraded, so comfort was not an issue. But as always, it is the people from baggage handlers, flight attendants, pilots etc. that make the difference.

The experience was great and much better than the flight going out. of course I was in first class but the service was excellent

Comfort of seats, ease of boarding. Food selection could be better

Food options were limited which is absolutely embarrassing for a Flight of this size The staff did not come around as much and I am not accustomed to such poor service from American Airlines Drinks I believe were limited to soda and water

Crew were attentive and friendly. Flight was smooth and early! I enjoyed the less crowded plane. Thank you!

Nothing, flight was supposed to leave at 758 am. My flight didn’t leave until 430 pm. Spent the whole day at the airport.

1st flight was delayed because of broken radio, missed connection but they got us on very next plane 1 hr later. Return flights were both delayed by 1 hr each. Crews were fine. Planes ok, but had to check carry ons.

It’s never made crystal clear if your flight will have in flight entertainment or not. That should be explicit

There was a male flight attendant who seemed like he was VERY upset the entire flight. At one point I went to the back of the flight with my 1 year old to get some space in an empty row, (she was not making noise) and he was sitting in a row where he could see us. He started huffing and puffing and throwing a tantrum, throwing the window shade up and down, and we were very uncomfortable. My husband also had a weird experience with him. I just don't think he should be flying when under such stress.

19 hr delay requiring a change to red eye. No lounge access without paying. Loss of seat upgrade fee.

Crew was nice and accommodating, but someone failed to inspect the plane before the passengers got on and we ended up deplaning and changing planes when this could have been avoided.
