I didn't realize they didn't have bathrooms on the plane. Almost had a very bad situation.

I didn't realize they didn't have bathrooms on the plane. Almost had a very bad situation.

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.

Terrible They charged me 157$ for excess baggage even though my bags were within the normally accepted limits Flight was late. Service was poor. The snacks were really bad

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 ok for the most part, it is missing something

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

Awful, horrible customer service. Flight got delayed and had to spend y the night in Bogota as a result. Very poor

We had 2 delayed LATAM flights in our trip. We were only given one coffee for 5 hours delay. Also when we were boarding the crew wanted to charge us for our allowed carry on luggage. I got a bit angry and they finally didn’t charge anything. Not flying with LATAM again.

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

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.
