Plane boarded and left on time or very close to the stated departure. Arrived on time. Staff was subdued. Could not hear the flight attendant too well. No announcement from the pilot which is always nice. Biggest complaint absolutely no little snacks! But the important thing is we left and arrived on time and we survived.
Crew was not happy to be there and neither was I 😭 well at least the lady that helped me.. I was stuck in the middle seat between two men. Totally my fault since I didn’t pay a fee to select my seat though. I recommend paying the fee even if you’re in a budget. It’s better than being placed aaaaallllllll the way in the back next to the smelly bathrooms. The seats didn’t recline either!! It was a red eye flight so I got no sleep whatsoever. Ordered a coffee and it tasted like…. Let’s just say it was horrible. I had to to return it to the same crew lady and she looked at me like this girl…. Sorry but I was not going to drink that- please take it back!! Oh and lastly, my luggage was completely broken and damaged. All wheels were missing by the time my luggage came around in the luggage cart. Lmao. Overall poor experience to say the least. Tickets were cheap though😂😂😂
Delayed flight both ways. Then, on the return flight, we were stuck on the tarmac for at least 30+ minutes. Idk what happened, but this was a bad experience.
Great flight, no bumps to speak of, pleasant crew, good inflight entertainment choices
Coffee or tea service would be nice for an evening flight, water or juice not good enough.
this flight had a 7 hour delay due to weather in NYC. It diverted to Pittsburgh for 2 hours then proceeded to NYC. Through it all the crew and flight attendants were terrific. They gave timely information, showed empathy , and were very professional.
seats good, foot space comfortable not good, waiting on tormack at Las Vegas
Paying for first class and then they want $8:00 for wifi.
fine. only problem,,,, for some,,,,was that many people started trying to exit from the back of the plane,, . lots of irate people. there should be a flight attendant mid plane..to be sure that doesn't happen. The crew up front had no idea what was happening. One big guy started it..then a bunch of others followed his lead. could have gotten ugly... One man stepped in and questioned those rule breakers.. nothing bad happened,,,but......
The cabin was quiet for the redeye flight. The area was clean. The staff was great. The 787 Max was in good condition. Drawbacks were that the seat widths were tight for some passengers. The seat padding was at best average and for a long flight uncomfortable.
Delayed flight. Nicest crew member was a SW pilot flying seated next to me who kindly move to seat the final passenger. Flight extra delayed. My cup of refreshment of ginger ale was so packed with ice it was literally 2 sips.
No trays in our seats, we sat in first row, purchased a business class fare. Had to hold our drinks and snack in our hands. No plugs for our cell phones. Had to pay for it a drink cocktail each. Seats so uncomfortable.
Flight wasn’t even full, but too many carry-ons caused us to run out of bin space. New bag fee has folks who would usually check their bags carrying on. Watching Southwest morph into Spirit/Frontier is so sad to watch
Southwest is Southwest. No frills. If you're luck enough to get a happy crew (we did), then it makes for a nicer flight.
It was a perfect flight in all aspects! Both legs!
Great flight, 47 passengers on a 180 seat plane. Stewardess was pleasant and cheerful.
I liked the crew member who gave flight instructions on "in case of a problem:. The seats are so small that only a young teenager could sit in middle seat.
Very good. Sad to learn Southwest is going start to charge for bags
Great flight staff. Ease of boarding. Overall, very uneventful and easy trip.
Stuck on tarmac for two hours plus a 5.5 hour flight. Rude flight attendant. And no meals, not even for purchase!
I learned that seating towards the end of plane that a line forms for the restroom and people use your chair as a hand railing, bumping your seat consistently. I was seated in the aisle. I think that next time if I am towards the back row I would want to sit in the middle or window seat.
Everything was great. Only thing that could’ve made it better was buy on board options for hot food, but the snacks were decent. The flight attendants were great. I had no complaints. I was able to make it to my destination safely
Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.
Very comfortable (upgraded to business class). The audio on my screen didn’t work, but I managed to play the audio through my phone while watching the screen.
Boarding seemed to be organized bedlam. For what ever reason, preboarding took longer than 20 minutes. Made the plane 20 minutes late taking off. Luckily we arrived on time. Flight crew seemed very friendly. Only slight turbulence.
The personnel were professional and friendly. The Boeing 737 Max 9 is too claustrophobic and was very warm at both airport gates, and still warm in the air.
While the staff was pleasant and helpful, the following observations are for your awareness. There was some delay on the tarmac on take off and landing. The paid lunch/food offerings were limited. Entertainment was only available on WiFi at a cost.
get E+, a must for 5 hours flight if you are tall
Compared with other carriers business class for an overnight was not worth the extra expense.
Unbelievable check in horrible. Asked to print tickets at the gate after a delay
check in at security was a hassle being scanned. Spirit employees were helpful and professional.
I liked how cheap it was but both my flights were delayed heavily
It was okay delay was long but I made it
I have never flown Spirit it was much better than anticipated!
Staff was very friendly. They attended to people nicely and reprimanded, in a professional way, to those who wouldn’t listen. AC wasn’t working on the flight waiting to depart in Burbank, so it was uncomfortable for a while since the flight was delayed but then better before take off.
Good on that leg. When I arrived in Detroit I had to wait over an hour for luggage.
The crew was very nice. I would like to see them offer basic refreshments just like a soda and pretzels, etc. for free.
I missed my flight because I was not informed that I had to check in 45 minutes before my flight and I was not allowed to check in any time after that. I was there at boarding time and their customer service was poor and they told me since I didn't check in 45 minutes prior, I couldn't get my boarding pass. I received an email containing my "e ticket" which I Thought was going to get me boarded.But but they said that was just an Itinerary and it was no good to help me get on the plane. I had already missed one flight earlier that afternoon and had to pay for this flight.And then when I missed it they told me it was gonna cost me another $99 to reschedule my flight
Seats uncomfortable, hard to check luggage, etc. It was like the last flight out of Hanoi
Boarding in Orlando was not good. Giant mob at the gate, should have been lines.
The ticketing agents were rude but then we had a great gate agent very nice we had to ride a buss out to where the plane was parked but it was in some back corner of the airport when we got to the plane the captain who was great btw was cleaning the plane because the same rude ticketing agent told them they we not contracted to vacuum the plane. The ride to las Vegas was fine We had a connecting flight to Dallas. The flight was fine but when we arrived in Dallas everyone who flew on any frontier airlines the picked up bags from baggage claim D15 had to wait over a hour for their bags to start we arrived at 11:30pm ish to the gate we didn't leave the baggage clamed till 12:50 am very not happy and i used to fly frontier 4 times a week for work in Denver i will not be using them again
I missed a flight because of a delay. I had to buy a new ticket through Southwest.
My flight was delayed by two hours which made it so that I would miss my layover flight. I stood in line for customer service for over an hour and when I reached the agent she told me to scan a QR code and it'll give me options. I wasn't offered any help, guidance or compensation, only told that I have options but that I had to figure it all out myself. I was refunded part of the trip and had to buy an expensive same day ticket from another airline in order to get home. I will never fly Frontier again.
Cancelled flight after I arrived at airport after 75 min drive and parking. Next flight was 4 days in the future. Had to scramble and buy a much more expensive flight on another carrier.
I liked the turn-style feature at gate 209B at LAX. Very efficient process. The gate staff also made several, clearly directed announcements so I felt very informed.
Although an hour and a half early was told by staff at check in they had overbooked and could not check us in for the flight.
The reps working at the airport counter were dumber than a second coat of paint.
My costume jewelry was stolen out of my bag. Got to airport and my bag weighed 45 pounds- 5 pounds over cost me $100 Long lines in tier one. No entertainment No WiFi no free drinks or snacks
The seats were awful, hard plastic covered in sheet vinyl. The airline tries to scam you into paying extra to get seat together when the flight wasn’t full. They were going to separate a family with young children but my wife who had a row to herself gave up her seat so the young mom could be with her young boys. I’m never giving this airline my money again.
