Quick flight and helpful crew both on the ground and in the air. Went super easy and fast.

Quick flight and helpful crew both on the ground and in the air. Went super easy and fast.

They misplaced our 1 bag and that messed up our reservation for the following day of fun and we paid extra 100 for the bag. Not fun

One of their flight attendants made a rude comment as I deboarded the plane. Definitely won’t be flying with them again.

Very below what I expect from Alaska/ On Feb 19, my foight JFK to Portland Flight was three and a half hours late leaving JFK (NOT due to weatherat departure or destination) In addition to losing this time, I then had to take a taxi home, rather than public tranist due to the late hour. This added $45 to the cost of the trip.

No seat assignment on boarding pass. Led to unnecessary confusion.

Not fond of smaller planes ( no737 avail ) Weather was some what of a factor (Bumpy)

Every one of the people at Alaska Airlines were helpful and kind. My complaints are systemic in the industry - small seats, tiny packages of pretzels (why bother?), and a general shabbiness that I attribute to the lion’s share of their profits going to execs and investors instead of building a better business.

no food was served - potential disruptive weather was claimed as the deferral

Very good. Landed on time got luggage in a timely manner.

They canceled our flight for 2 days. 8 hour wait each day to reschedule flights. Everytime we reschedule it would get cancelled within a few hours. We were stuck in Portland for 2 extra days with nowhere to stay. Horrible experience. I want a full refund and I want retribution for our troubles. I am extremely upset with my experience. They finally got us on a flight with Hawaiian airlines.

Carly the flight attendant was extremely helpful and very accommodating to passengers on the flight from what I noticed. Couldn't be more satisfied with the service and assistance from Delta's flight attendant, Thanks again Carly!!

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

I didn’t like that I could not select my seat and was assigned a seat when I checked in at LAX

Delta did an awful job w logistics at DTW. Missed connection. We were there an hour early. SUCKED

Inflight entertainment stopped working as we taxi to runway and never worked again until landing and taxi to gate. Grrrr

Had to run to make it only to have the flight delayed to wait for all the late connectors Second drink service skipped up

Boarding was a sh!t show. JFK BOARDING was awful. The agent called three sections at a time Clogging the area then yelling at people to not block the walk way. How are you going to call delta one , premium select and comfort plus at once and the yell at highest paying passengers. Need to do a lot better and the flight attendants in the galley need to understand that their voices travel. They were talking about others and everyone in the cabin heard them

Uncomfortable seats on 14 hour flight. Mediocre food. On time and great crew.

MSP to Atlanta was much better than Atlanta to St. Kitts. Paid $180 each for myself and wife for Delta comfort from Atlanta to St. Kitts. Seats were more narrow and obviously old and worn out. Tailbone is killing me. Seat would not recline. Seats behind reclined and we were not an exit row or in front of an exit row. Entertainment did not work in that the movie jumped forward and back and there was no audio. The plug in the arm rest was loose. Flight attendant tried “resetting” the video for my seat but no good. She never checked back. Someone else near me had the same issue. Touch screen was unresponsive. No where near as comfortable as MSP to Atlanta flight. 3 plus hrs. flight time without the basic amenities and not even remotely close to comfortable but paid for Comfort plus. I will be very disappointed if I have the same on my return “Comfort Plus” flight St. Kitts to Atlanta. At the very least my wife and I should be refunded for round trip “Comfort Plus” charges. Please feel free to contact me directly for more details.

public website still broken for years randomly blocking browsers with privacy options active after loading a page maybe once. check-in on laptop was almost impossible but eventually randomly worked. had to print pass at airport since couldn't get back in to load digital pass on mobile firefox or chrome. red eye flight so smooth onboarding, plenty of room to spread out, easy offboarding. onboard wifi instructions mention vpn can cause problems connecting but fails to also mention private dns. no printed or built in menu list, seems weird to require personal device to point at qr code link for menu which does not even allow direct ordering. people with health condition risk related dietary restrictions trying to avoid for example cholesterol and sugar are left guessing what they can order either way without nutritional info highlights (cranberry juice was minute maid cocktail with as much suger as typical can of soda). tap to pay wasn't working and always seems sketchy to manually enter card info. good movie variety, so limited tv was okay.

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.

I flew from Las Vegas to Reno Nevada. Airfare was 60 $ round trip. I needed to bring my skis and boots.that was going to be $111 to bring them. Upon arrival they informed me that anyone who has skis more than 62 inches long is charged an oversize fee of $150 each way. Almost everyone over 5 foot five has skis over 62 inches long. So I paid $60 for the flight and $411 to bring my skis with me! WTF

Didn’t make the connecting flight due to a delay on our first flight.

I like the price. I did not like the seats: very little space and not reclining.

Flights are great except for the ticketing service on the terminal.. Too little employees taking care for lots of flights.

The seats were very uncomfortable. The crew was very polite and helpful.

The airplane was extremely hot the air conditioner wasn’t working I

The text told me it was changed to Terminal E and Gate D5. But with no one on site to ask questions there was confusion on where to go as all the gates were E's. Then we took the skyline to the D area. We left to get something to eat. No announcement was made but my daughter happened to asked and they told her our gate was moved to D12. I will not fly Spirit again.

Seats horrible. No way of getting comfortable . But flight ran smoothly
