This airline always trick us so we end up paying again for the luggage’s. This airline is worthless and take advantage of travelers .

Now days most airlines flying to Central America have a really poor service, but if you buy first class they will treat you better. I miss those days when flying was fun.

Friendly staff at all very easy check in and organize process

Horrible airline, upgraded to sit on seats made of stone. Staff were rude and on top of it they charge an arm and a leg for luggage 🧳 never again

The seats are the worst I upgraded to premium big mistake and it seems like no one likes there job very unpleasant

they don’t have TV Seat to Type in space

Very old flight - time to retire it for newer airplanes

From pre boarding to flight attendant, crew and baggage handler, excellent. Didn’t lost my luggage like West jet.

Do not like the size of the overhead bin. I think staff should monitor the size of suitcases that are being carried on by passengers to ensure they meet the size requirement.

Everything except the food and entertainment. It was a great experience though

Delayed, toilets did not flush, pilot parked to far away from Gate

Check-in, boarding and the flight from Phoenix to Houston was quick and easy. The flight from Houston to Shreveport was delayed 5 hours. It was frustrating but I think United handled it the best they could.

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

In Liberia airport 5 min before our departure the airport was closed for takeoff for 30 min. Upon arrival to IAH we didn’t have any available gate and waited taxing another 40 min. As a result we arrived for 1+ h later. The walkway to the passport control in IAH is about 1-2 ml long. After the passport control you have to pass the security check again. Only 3 out of 16 checkpoints were open and the line was enormously long. As a result, even though we supposed to have 2.5 hrs gap in between the flights we missed our transfer. United rebooked us for the next available flight early morning and provided free hotel and meal vouchers through.

United is an incompetent airline. They parked the plane on the tarmac for an hour after arriving because they “didn’t have a gate available” it was actually some sort of lie because as we de planed there were approximately 9 open and manned and empty gates that we walked past. Many people on the flight missed connections for the hour long sit on the tarmac. Utterly baffling and incompetent behavior from United flight ops.

I boarded flight UA#1318 at Sacramento International Airport going back to Houston TX. The flight was scheduled at 5:10am. I was able to check in virtually using the United Airlines app. When I entered the airport, there was no one outside assisting with checked bags as it was for Delta Airlines. Immediately upon entering, there was a LONG, EXTREMELY LONG line to the kiosks to get boarding passes. I stand in line to get boarding passes then had to move to ANOTHER EXTREMELY LONG line to get my bags checked in. While standing in this line, we noticed an agent taking customers to 3 at a time to her station to check their bags in. Lucky for me, she called me back, checked my bags for me and I was on my way. I then encountered another long line at the TSA check and to avoid I ending up having to sign up for CLEAR to bypass it. So glad, I did.,...Both of my flights were great with no issues, butthe check in progress at Bush Airport was so much smoother. Check-in at SMF airport needs to be anaylzed and corrected. Do better United, I know you can....thanks

Horrible experience with Avianca, they delayed their flight and when we arrived to NYC, AVIANCA took 1 hr y 30 mins to park the airplane and all passenger get off the plane, it made me lost all my trains to get back home and I came back to my place at 3 am instead of 12 am. On the top of that their plane seat are so uncomfortable and is not enough space and killed my legs and knees, Avianca used to be good when it was a Colombian company, now after Brasilian company bought them, their service quality is bad and their flights are delayed and oversold.

Not good, tried to purchase a first class upgrade and they couldn’t get it done. Was super uncomfortable the whole time.

We waited for one hour to deboard the plane after landing. That could be better

I handed in my suitcase in perfect condition at SAL Airport. And in MIA Airport I received it with one corner broken and the wheels bent.

I like the crew members they're very friendly. Clean plane. The flight was on time. I dont like the comfort my car seat its better that the plane seats. They charge for everything. This airline was very good. Now it's a low cost airline

6 hour flight and have to pay for everything 100 dollars to add a carry-on bag is insane

Did not fly with Pakistan International Airlines. Have never flown with Pakistan International Airlines.

Boarding, crew were excellent, food was ok and entertainment need to improve

The check in is the only positive thing in Avianca. The seat is the most uncomfortable I have traveled, the distance is minimal.

Not what it used to be. The sale of food makes them look greedy!

They cancelled the flight due to crew unavailability. The next day they cancelled the flight again.

That gate is like a ducking shelter at Newark No where to sit Outlets that don’t work Bathrooms that are dirty

For the cost you can't e too critical, but the inablitiy to recline the seat and minimal cushioning in the seats made for a less than comfortable flight. Other than that we had an ealry departure and arrival, boarding was smooth.

Horrible experience. First and last time using this airline. Made an announcement that boarding will start in 15 minutes, canceled the flight 5 minutes later due to no airline staff. Had to book another flight on Delta since Spirit had no other flights arriving to my original destination the same day. I wouldn't recommend anyone to fly with Spirit. No wonder why it consistently ranks high among worst airlines.

The plane was supposed to leave at 12:59 Amma and another plane took us around 9:30 am. There were 7 delay announcements. We were to receive a voucher of $12 back to pay for food at any place in the airport. One passenger tried to use the voucher was denied. I did not receive the voucher for me, my son, and grandson. I went to the desk and informed them and they took my phone # and email and they told me to wait. I did and was never sent. The plane was uncomfortable, the crew was dismissive of anyone beyond the last two seats. I will NEVER fly or recommend Spirit Airlines again.

I knew what I was getting into, but never again. Hour long bag drop. 1.5 hour delay. 1 hr 45 mins sitting on the tarmac after landing. They lost a bunch of bags but luckily not mine. Awful experience.

Loved that all flights were om time or early. Hated all the additional costs for a seat and luggage.

Our flight got rescheduled 48 hours later, the airline didn’t pay a penny for our expenses.

My baby was crying uncontrollably for the longest time and the entire crew was SO supportive, I’m so appreciative of them. Thank you so much for the support during an exhausting moment. We got very lucky.

Uncomfortable seats and tiny tray table. Expensive snacks. Flight was on time and crew was pleasant but take me back to Southwest!

This is my second time flying with Frontier. My current experience was very favorable. The staff from the gate to the plane was friendly, warm and professional. The food options lacked in my opinion. This area needs some attention in my opinion.

Frontier line changes my flight schedule with out my authorization. They never ask me and with out my concern they cut off 4 hours of my vacation they force my to leave 4 hours early from Puerto Rico.

There was no food and no entertainment, so I'm not sure why these are even in the survey, as my understanding is frontier does not ever offer food without a few, not even a snack, and there are no screens so unless the flight safety talk is our entertainment why ask how we liked it?. One of the flight attendants say in the back of the plane as people filed in to their seats, yelling orders about where to put baggage and telling people to hurry up. It was the least professional experience I've ever had on a flight.

Very well recently! Frontier is improving and less harrassing customer on luggages! Positive!

Good for a budget airline! It was easy to get on, staff was really nice. Can’t say anything about the food or entertainment because it wasn’t available, which is fine.

I am writing to express my disappointment with my recent Frontier Airlines flight. I was charged $99 at the gate because my bag was said to be too large, yet once onboard there was no available overhead bin space, and I was required to place the bag under the seat in front of me anyway. This made the charge feel unnecessary and unfair. Additionally, before the flight even took off, I was asked to move from the seat I paid for into a middle seat so another passenger and her cat could have my seat to themselves. I was not offered compensation or an explanation for being moved from a paid seat. Between the unexpected bag fee and being forced to give up my seat, this experience fell well below acceptable customer service standards. I would appreciate a review of this situation and appropriate compensation.

It was costly and difficult to check in. $85 to take a small suitcase with me, carry on or checked and $75 on the return trip, Plus $25 if I didn't check my self in check in $25, because I couldn't do it on the kiosk. Small very uncomfortable seats, waited on the runway for near an hour each way. It was my worst flight to date.

It was ok. It was expensive to check 2 bags ($75.00 per bag), and then it took a long time to wait for shuttle to take us from one terminal to the terminal where the plane was taking off at LAX. And all of this for a flight where we had to pay for any food or drink that was not water.

It didn’t happen. I booked it and then was told it wasn’t available and then forced to pay far higher prices for a worse option

A 630departure flight Delayed 6hours! They changed my gate, I moved to the new gate. Had our flight on the screen for 12noon departure. I go get above to eat, check screen again and the flight was gone, no notice no announcement, nothing!! They sent my bag on the flight I wasn’t on, got it back to me 3days later. Thank goodness they did refund my money but I will NEVER fly them again.
