The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

Had a broken tray in business class. Crew just shrugged it off.

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

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.

Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.

Flight diverted in SD. Later take off in Seattle by 1.3hrs

Mi primera conexión se retrasó por lo cual perdí mi segunda conexión la cual salió adelantada

Crew was not friendly when I went to request a seat change.

There were choices for the snacks. Good choices and tasty lunch and breakfast as well.

The flight crew was amazing. I’m very tall and they moved me to an exit row unsolicited!!! Amazing service.

The plane was so outdated, that it made it uncomfortable. The temperature was hot during the whole flight

Some entertainment and food/snack service would have been nice

All the pessengers should be wait in a line útil the creo and piloto are arrived.

Planes seat could be bigger very uncomfortable for tall humans.

1 hour waiting for suitcases to come out traveling in business class and food in business class is a sandwich? Avoid Aeromexico .

No space reserved for anyone who didn’t have underseat in front of them. Made it inconvenient to get the backs secured. No inflight entertainment in the 190. Bring your own! Food was excellent and we were surprised to get a full breakfast.

Cons: "left Houston more than 2 hours later, arrive in Mexico over 2 am"
Cons: "El problema es que nunca pude cambiar mi vuelo y con ustedes fue imposible comunicarse para que me auxiliaran. Muy mal por ustedes no por la línea."
Pros: "The crew was amazing , the site is ok"
Cons: "I love Aeroméxico , thanks for de service and the food."
Pros: "Plenty a space between seats. Ver confortable seats and small entertainment screens!"
Cons: "Better selection of movie?"

They offered food. The crew passed by again offering water. I enjoyed the two seating section. I think is very comfortable instead of the three seat way, unless you seat in the middle; which it's not bad, but I wouldn't prefer. All and all, I think the lay out of the seating rows are better than other airlines so far( I haven't tried many anyways). The lay out makes the getting in and out to use the restroom less uncomfortable and cramped. First time flying with Latam. I will fly with them again

Everything was as you would expect in coach - fine. Flight was close to on time.

No air in the middle rows. Had a hard time breathing. Was dying of heat.

Horrific checkin procedure with neither Delta nor Latam figuring out how to check me in. 4 hrs on customer support with both and both airlines pointing to each other who should do checking. I was not checked in until morning of flight, which for international flight is concerning.

It was a good experience, the flight was a little too long & the food was ok

the flight from Boston to Curitiba was on time actually 30 minutes earlier. latam was not able to unload the luggage for custom checkup in Sao Paulo ii took two and half hours . i missed the flight to Curitiba spend the night in hotel and then flying in the morning to Curitiba

Tough flight with turbulence… I was told by a fellow passenger that it is common. Nonetheless, very stressful. Cordial staff.

Very unprofessional staff in the checking and boarding. There was no space for my carry-on bag, which is understandable for a full flight. However, the rudeness in answering my questions about my bag were unnecessary. Shaming and threatening a passenger to be left behind was something I had never experienced (I am 57 years old and a Skymiles member) before. At a minimum, the boarding staff (Krystal Mejia and her manager Dee) should undergo further training on cultural sensitivity and professional skills on speaking with passengers. Krystal, just because I have dark hair and “look Latina” does not mean I can speak Spanish. Your assumption and threatening words until the very ending of my boarding (door of the airplane) were not only unnecessary and stressful but something that a passenger should not experience before boarding.

The flight from PDX to New York was cancelled, and I got rebooked one day later. Because of this I missed a meeting at my final destination, EZE. I now need to stay longer in Argentina, and was told the tariff difference was $780 plus $150 penalty! I am not using my return ticket, and have purchased a one way ticket EZE-PDX for $606 with another airline. SHAMEFUL

Cons: "Would not let us board with 25 minutes prior to departure Because they lock their doors 35 minutes prior"

Not a fan of the diagonal partially enclosed business class seats or how they have to be converted to beds manually by crew. I prefer more isolation and user control for switching to lie flat.

No lounge access with “United First” ticket. False alarm about late flight, jeopardizing connection. Wrong meal. Loose power socket would not hold plug, could not charge device. In-flight access to text messaging did not work. Toilet seat on plane would not stay up.

We ended up with seats in the very back. So they did not recline. Have no idea why, we reserved and checked in very early. The isles were very narrow and the seats had very little leg room. But they did give us water, and a snack.

Energetic crew - flight full of swiftied going to Taylor's opening show in Paris! Long lines for bathroom made out kind of suck though

Check in etc was very good. As for on the plane, it was like flying in a freezer. It was so cold, i have flown for years and never been so cold on a plane. Staff on board said its always cold when flying which is a load of rubbish. They wouldnt put any heating on and now i have the flu because of this .

I’ve had a couple flights this week on United that were delayed by an hour or more

Flight was delayed 2.5 hours - a big deal on an overnight when you plan to sleep.

I feel like they have upgraded the app since I last flew United and I found it to be super helpful. I had stopped flying United unless absolutely necessary and my experience on this trip indicates they have been working hard to improve their services.

Surprisingly easy! I was hesitant to try this, but the cost swayed me. I actually felt like I had less stress than all the taxiing and possible delays that occur with short regional flights where you spend less time in the air than getting to and from the plane..

This flight was delayed multiple times and eventually canceled around 2-3ish. Original take off time was around 10:30am. By 3, there were no other options out of Houston, so stuck in Houston for from 3pm - 11am the next day.

Liked - nothing. Disliked - delayed 35+ min sitting on the plane. Caused me to miss my connection in Charlotte. American Airlines is the worst US Air Carrier company with atrocious customer service.

Worst situation ever! I booked my tickets for this trip on Alaska Airlines. I guess AA is a partner and we flew nonstop from Eugene to PHX on an AA jet. I had to pay for luggage from PHX to EUG. And this was an Alaska Airlines reservation paid for with Alaska airlines credit card! Got to the PHX airport and was not able to check bags because of some weird issue with the AA software. My reservation had to be the-entered by the agent. I will never pick another American Airlines flight on the Alaska Airlines website. While on vacation, I tried to upgrade our seats for the trip home. The request just buffered and never went through. I tried four times and was charged four times on my credit card. The card was charged but the seats were never changed. What a wreck!

Left from gate 30 minutes before flight. Never been late to a flight ever. It says 15 minutes before explicitly on the ticket.

I like the boarding process, it was fast. The seat doesn’t have a TV for a long flight and food wasn’t served, just snacks.

Use planes with TVs on flights over 4 hours. The free entertainment was a cheap in between solution for a very long flight that you don't even bother providing meals or decent snacks.

Even though we left CMI late, we mostly made up the time.

Delayed almost 4 hours for a 45 minute flight with no explanation.

Again, multiple delays and I eventually just canceled and drove!

Great crew. Very comfortable business seats with nice bedding. Good food. We were delayed to let late passengers on the flight, but otherwise great experience.

Great crew. We were delayed so that late passengers could get on the flight. Love the bedding in business class. Good food. Great experience.
