Airline reviews

I was told that they needed to check my bag at the gate and to pick it up at the gate in Richmond. No big deal. I know they can't control the weather, but we flew around RIC for 45 minutes to avoid the storm and were 25 minutes late leaving as well. Once we landed, we were told to go to baggage claim to pick up our luggage. I went to bathroom, paid for parking, and went to the assigned baggage claim location. United flight people came down with us as well. They got their luggage immediately. Next, South West people came down about 10 minutes later. They got their luggage next. We finally got our luggage around 30 minutes in waiting. Was not a wonderful experience. No reflection on Delta, but the ground crew was lousy at best.

Everything could have benn better. Short fly, no food, no entertainment and no wifi.

Flight delayed. Air broken. Cabin was hot enough to pass out. Delta shuttle’s becoming worse and worse.

my mom urmila patel needed a wheelchair which was not available on the curbside. she needed to walk almost 50 meters inside (at the risk of falling) and then had to wait in line to get a wheelchair (this is not ok). Once obtained she had to seat in it for 30-45 minutes for someone to take her in thru the checkin process (which was fairly smooth and easy). the lady who helped her with her checkin process was very courteous and helpful

On the return flight, flight attendant Britt went out of her way to inform passengers that several of us had tight connections.

Fast, lovely scenery, great info on the Delta flight screen about landmarks we were flying over. Great landing!

Staff at the check-in counter were friendly, happy and helpful. They tagged our bags and sent us to “bag drop off” but were not very clear about where that was. The airport was busy we headed off in what we thought was the right direction until a gentleman waved us down and actually came after us. He was the baggage handler for Delta and recognized our “deer in the headlights “ look-he brought us to the right area (which was marked as the Southwest Airlines Drop Off) and sent us on our way. Wonderful guy, low key and working with a big smile on his face. Loved it. Loved him.

During the flight, the only refreshments provided were crackers and soft drinks; no substantial food was offered despite the international route. Furthermore, our initial flight was delayed, causing us to miss the connecting flight in Atlanta. The airline did not hold the connection, and we were informed that the next available flight is not for another 24 hours. While I am aware of alternative options via JetBlue, they operate out of JFK, which is not a viable solution for us as a resident of New Jersey.

Arlene was a great flight attendant. I also liked how one of the other flight attendants gave us a heads up about snacks and asked everyone to remove their headphones when it was their turn to order. Good idea.

Long flight but comfortable and not freezing as I have experienced on Hawaiian flights to the islands. They gave us blankets just in case. Nice touch.

Honestly first time flying with delta and it was pretty good. All the process very smooth and crew was always nice and attentive.

Nothing I like, I missed this connection b/c of an earlier flight delay. I had to stay one more night and I paid out my own pocket. LATAM failed to send me to a safe and decent hotel.

Deleted flight made me loose my connection flight now stuck in Atlanta for a day

Apart of Sky miles delta. And they go everywhere in Brazil

We were not allowed to carry a bottle of water onto the 8 hour flight.

We traveled with two young children, and it was not possible for our family to be seated together. No one offered help or assistance to organize seating so we could sit with our kids. In the end, we managed to find two seats in Economy so I could at least sit with one of them, even though I had originally paid for Comfort+. In summary, I had to downgrade my seat just to be able to sit with one of my children, which was very disappointing

I booked a flight through Kayak to Brazil I have traveled to Brazil several times before Kayak Delta or LATAM never mentioned during the booking or in the pre flight process that the visa requirements to visit Brazil have changed earlier this year. I was unaware of this change and as such never got a visa and was unable to fly from JFK to Sao Paulo Add to this that Delta allowed me to fly from Boston to JFK which they should not have as I didn’t have a visa. It has been a terrible experience and a huge loss of money

The assistance we received and the flight itself was wonderful. We will fly with LATAM airlines again, in the future.

Latam may be the worst airline in the world, far worse than even the lowest of low cost airlines in the USA. I wasted hours trying to PAY THEM TO CHECK A BAG! Then they misled me at the terminal, sent me through the wrong security line, the list goes on and on... Just absolutely terrible in every way. Avoid at all costs.

I’m entitled to a refund per LATAM due to the mid flight itinerary change and being stuck in São Paulo for 24 hours and needing to get a hotel. The airline was dismissive and of no help.

Good quick flight on a small but comfortable plane. I'm 6'3 and had plenty of space.

The flight was delayed so we were dead tired, and after that the turbulence was horrible. I was very scared.

Wonderful. Quick boarding. Early departure and we arrived 30 minutes early at our destination. Unfortunately, when you arrive early, there is still a departing aircraft at our gate. We had to park for 30 minutes until the gate was clear. So our early arrival was not really early at the gate. Otherwise it was a quick and smooth flight. Appreciated the efficiency.

Wifi took a while to kick in and we had a maintenance issue that took over 40 mins at the gate in Washington before pulling back

Very good. Because of the delays with my previous flight, I missed my connection, but I was able to book another flight through the United app easily.

Was happy we finally got upgraded in 1st class. The seat getting old. The cushiness need some improvement.

Ineffective communication with United resulted in lost baggage. Their Baggage Tracing counter at MUC was shut down from 11:00-14:15 on my arrival. Undertrained, underinformed staff had me Running all over MUC to find someone to help me to no avail. Staff was rude, unhelpful, and unable to effectively use the systems they did have operational. They refused to contact United in any way or provide any accommodation or other resources while I waited for my luggage. This has destroyed my downstream itinerary. If they had even the slightest visibility I may have been able to reschedule/plan, but again, their staff provided nothing, and did nothing more than their website, which doesn’t even work on a standard phone browser. Miserable failure at all levels that weren’t associated with the operation of the aircraft.

Sat next to a one year old. She crawled all over the place and made me laugh.

The Crew and the food was the worst I ever had in Business Class. First they told us there were no space for carry on. It was plenty of space over our 2 row seats, we had to ask to let us travel with it which was accepted. They were aware that we had to run for the connection due to the previous flight delay. Have us one hour waiting for more customers and not even offer a glass of water. Then started the service and they started to serve other passengers drinks in business and did not offer any drinks until they serve our pre ordered meal and I ask for something to drink. I had to wait until they finished to serve all passengers until Inget something. The crew was the worts I ever had for Business Class in my life.

Not great experience - we were super late boarding due to issues with aircraft. Then when we finally all got onboard and seated and they started taxiing out to the runway they just stopped then turned around and went back to the airport. Apparently the crew “ran out of time” to legally fly us. They mentioned that they were about 2 minutes away from taking off. I understand the rules and safety but kinda wonder why they would have bothered boarding us in the first place? Had to go all the way back and de plane and then wait in a HUGE line to get a hotel (this is somewhere around 2:30am) finally got to hotel by Uber (no shuttle after 20min so gave up) and they ended up putting us all back on the same aircraft at 10am next morning so got about 2.5 hours sleep. They did give us. $250 credit, but it was a São Paulo Brazil flight out of Dulles. The flight and everything was fine.

I specifically choose not to check bags to ensure I can proceed directly to ground transportation upon arrival. However, due to a recurring lack of cabin space, I was again forced to gate-check my rolling luggage after going through my luggage to take out electronics and batteries. This practice unilaterally changes the service agreement made at the time of purchase. JetBlue needs to find a better way to manage overhead space that honors the carry-on baggage allowance.

Still hasn’t left. Why are you asking how it was?

Flight was good wish there were more snacks options for such a long flight but stewardesses were very pleasant as was flight crew.

I was denied a plastic fork to eat my food and was told plastic forks are for paying customers who buy Jet Blue’s food. So I had to make a utensil out of a cup so nourish my body. Like a refugee. Because decency is dead.

I was especially impressed without efficiently the crew got passengers on and off. One of the stewards was slightly gruff, I thought. No big deal but that's what I noticed.

Absolutely horrible. Flight was delayed 4 hours and they had no clue what was going on.

Onboard functioning wide-variety entertainment on a budget and having an open pantry is nice. Seats are not comfortable but go provide plenty of legroom for a 6'2" 260lbs man.

Even though the weather made a lot of flights become cancelled Jet Blue made the flight that was supposed to leave at 9 pm and we left at 12:15 am and I was so grateful- Thanks to the Senior Jet Blue Staff who made those decisions

Worst customer service ever experienced on the planet, dirty plane, no communication, and severe delays

Flight cancelled 2 hours prior to boarding. No explanation. No refunds.

Early morning flight and no food in First Class except a "salmon" box. No thank you. Was informed before take off by Captain that the plane was not serviced before we boarded in Phoenix. How does that happen? Need more frequent additions/turn over on the Entertainment. Thanks

Moved to earlier flight which unexpectedly had maintenance issues initially indicated as quick fix to ultimately plane changes. Moved back to original flight, also delayed. In all cases customer updates and communication very unclear, no updates on drivers for delays.

Delays with no explanation. It could have been handled better.

Flight delay for mechanical. Inbound arrived on time. No one said why mechanical delay.

Flight boarded, departed and landed on time. Excellent service from flight attendant in FIRST

This was one of the most frustrating travel experiences I've had to date. I had changed my flight day of to this one as it was slated to depart on time. It ended up being so delayed that my original flight took off before this one did. The boarding process began but eventually stopped and everyone had to get off the plane as a problem was identified. The person at the front desk just tried to laugh it off as if this wasn't already a huge inconvenience. From there, we eventually got to board only to sit at the gate for an additional hour because of some additional issue. This was extremely frustrating and caused a lot of stress.

It was a little concerning to hear the ground crew arguing with the flight crew over baggage space. Instead of taking them and checking them, they started checking for space in the first class cabin moving items around like the flight crew didn't know what they were doing. I was embarrassed for them.

delayed due to weather. Could not communicate with family since the wifi was broken

I got sick nothing contagious but distressing and the care I received by Kayla? Keighly the flight attendant will be memorable for ever. Thank You

We were told the flight was delayed 5 times, then it was moved to the next day.
