The staff were great and the layover times were excellent no multiple hours. I just hate the Boxed Water. So you really have to purchase high price water in the airport.

The staff were great and the layover times were excellent no multiple hours. I just hate the Boxed Water. So you really have to purchase high price water in the airport.

I like that we took off on time and arrived a bit early. I like that I could gate check my bag and board early. I don't like how crowded the flight was. I had ok leg room, but could feel every move of the person next to me. And the aisles are very narrow. The gate and flight crews were terrific.

I appreciated the ability to choose between multiple flights both into and out of Portland from Burbank on the same day, so we were able to attend an event and return without spending the night. I am unable to appreciate what Alaska Air calls "streamlining" the checkin/boarding process at Burbank Airport. If you have a smartphone and the Alaska Air app, it is probably fine, but removing the option of using onsite kiosks to print boarding passes does not meet my definition of "streamlined". I also found it challenging that both Portland and Burbank airports required the plane to sit on the runway for some time due to lack of an open gate at which to disembark. It would not be so bad if we could at least remove our seat belts and move a little bit while we waited, but that is not an option. I honestly don't know whether this is because of how Alaska Air operates, or just the circumstances of the particular day and airports we were using, but I normally do not experience these kinds of delays to reach a gate using Southwest Air.

It was not a great flight. There was a software update delay which had us on the ground for almost 2 hours. I was unable to make my shuttle to my final destination.

Both flights were delayed. We sat on the tarmac on Boise for 3 hours with little updates

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.

4 out of 4 flights cancelled or delayed. 5th trip with similar experience

the departure got delayed due to SJC situation, but it was a quite good waiting thanks to Alaska airline teams.

Lost luggage and no compensation. Did not receive luggage till 9pm the next day. Again no compensation or apology

Seat width is getting ridiculous. I don’t like having to twist myself into a ball to avoid my neighbor. It has gotten so bad over the last few years.

Seat back monitors and outlets were dead and not working.

Everything was great except for the seat. The backrest would not stay in the upright position.

I usually have a positive experience with Delta. Complimentary upgrades are always nice!

Flight delayed about 2 hrs so it made it a VERY late night

It was a crowded flight. They did the best they could.

Service was good for such a short flight. Small plane but smooth flight.

Worst flight in my life. Only was scheduled for a 45 min flight to get our connection flight. It was late by 40 minutes and we missed our connection. Delta was totally useless trying to help and unable to get my family on the next flight because they overbooked it Thus had to get a hotel at my expense and lost a day at Disney as a result. Cost me about a $1000 if you add 2 hotels meals shuttles etc to get thru the day Awful customer service by Delta in Detroit totally useless people

The experience was good and the flight departed on time and landed early

The flight was delayed but we got to our final destination.

Boarding was great. The flight landed early. It took the crew over an hour and a half to bring out drinks. I paid to upgrade my seat to Comfort+ only to be near a crying/screaming baby who was seldom quiet. Noise-cancelling earbuds didn’t even help. Waste of money to upgrade.

Trip was smooth bumpy from the wind but no issues at all the crew attendant was very pleasant and had great customer service

The customer service was excellent! Check-in, baggage check-in, boarding, the flight went very smooth.

Awful. I got stuck next to a person carrying a dog and behind someone with a dog. People need to board these dogs downstairs. The cabin is crowded enough with your pets

It was delayed several hours which delayed our connection in Denver. Not happy.

Ok, but comfort was lacking as the seats were way to small

All good except paid for wifi that did not work

Some of these FA’s need attitude check. Snarky bitches

The plane boarded and deplaned twice before the crew timed out. Flight was 7 hours late departing. Horrible experience!

Got automatically assigned middle seats unless you fork out extra money for a seat assignment, not impressed.

Flight was canceled 12 hours before take-off due to “weather”

No problems with flight. Even though I had a short layover in DFW, I was still able to easily make my connection.

Good flights. Departure and arrivals were on time. DFW was a little problematic in that the Skytrain without prior notice bypassed the Echo terminal so that delayed my arrival at my connecting flight.

Late boarding to clean plane from previous flight; initial boarding announcement not loud enough; fantastic cabin attendant front of plane

Delayed flight, few announcements with information, no comps, cluster f boarding because zones weren’t spread out and announced loud and repeatedly, staff did their job -nothing more nothing less, annoying kids were speaking and kicking the heck out of the back of my seat and parents weren’t willing to parent… so another typical day of air travel in the US.,

Gossipy flight attendants talked the whole flight about bar hopping and dating.

Turbulence was bad and flight attendants gossiped about going to the bar and dating. Could have better awareness.

Didn't like the 6 hour delay as it caused me to miss all of my connections. Still, I did get home safely 14 hours late but exhausted.

Flight attendants had no personality! The looked miserable! My seat was broken in first class. I can’t believe how American Airlines changed. 😞

pleased with overall experienced, but seats in coach are tight.

The staff was unprofessional and didn’t communicate very well. The boarding process was very disheveled, potentially due to a power outage the previous day but there was no contingency plan to properly get passengers boarded the following day. Once boarded the aircraft stayed on the tarmac for over 45 minutes due to high winds. The communication was sporadic but an announcement was finally made an additional 30 minutes later that the flight was cancelled but we couldn’t get off the plane. Prior to deplaning one of the gate agents came on the plane and made an announcement for everyone to pickup their checked bags and take a card to rebook a new reservation because they didn’t have adequate staff. Flights were missed, passengers went to different airports and there was little to no assistance from AA.

On time and fast. Overall it was a pleasant experience.

3 hour delay was brutal though not Spirit Airlines fault. the control tower would not let us take off because of weather

Beware of all the extras. Nickel and dimed. Everything was extra. It turns a $90 fare in to a $400 fair quite easily.

No basic services such as water, snacks. Internet very expensive. Seats were very small, hard and uncomfortable. Alaskan Airlines, my outbound flight to Boise from Orlando, offered beverage service, a snack, and reasonable priced internet, for the same price as my return trip on Spirit. It had more comfortable seating also.

It would have been nice to have been on the flight

Delayed several times. Flight was to arrive at midnight and it arrive at 3 am. A 3 hour delay is already bad but one that has you arriving in the wee hour is just disruptive and overall unacceptable. The complete lack of restitution is a joke in keeping with Spirit’s reputation of ranking bottom-low in the pecking order.

It wasn’t as horrible as I would have expected, however, to not provide water and change so much for bags is a ripoff to say the least.

Cancelled my flight , currently stuck in Houston and will likely miss my cruise

The flight attendants were very personable, extremely friendly, and had a very good feeling of the energy around them not to mention they’re very funny and engaging. What made up for the discomfort of the seats and the fact that the plane sat for a long time on the Turmac. Not sure if the pilot was new, but the landing was very rough sort of like I was at a magic mountain theme park ride that was built in 1959

Unfortunately not great, my flight was canceled with no notice given. I attempted to reach out to spirit airlines and have yet to receive any correspondence. I then had to book a new flight at two times the cost of the original.
