When booking, the connection times seem fine. But in reality, my two connections were cut short by the first leg being delayed due to issues at the destination (too much traffic going into SFO, ORD) and it became extremely stressful.

When booking, the connection times seem fine. But in reality, my two connections were cut short by the first leg being delayed due to issues at the destination (too much traffic going into SFO, ORD) and it became extremely stressful.

Promised internet. Tried for nine hours to log in, no way. I tried the free option, I tried the paid option, I tried restarting my phone.. several times! Very aggrevating as I was trying to keep up with an emregency medial issue with my dad, but could not because the promised service was not available.

I had bad experience with United airline. No live rep, they only have AI that respond to customers concern

Flight and crew were great. Need more legroom and do not allow seats to recline.

We arrived to Chicago nearly 30 minutes early, which was great, but then was on the ground for over an hour because the gate was not available. The issue I had was the pilot estimation was frustrating. First he said he was informed it would be 20 minutes but he said "it will probably be more like 10 minutes". After 30 minutes he came back on the comm and said it would be another 10 minutes, maybe 20. I understand he was only giving estimates but he also layered in his own gut feel. We were never told why we didn't have a gate even after our scheduled entry.

Just sat on the run way after we arrived early

Lounges are packed and very poor, food is really bad, for business class in an airline is well below expectations

Excellent all round, first time flying United. App is very helpful.

Unfortunately this is not a happy ending comment. Positive: flown United before no issue Negative: it only takes one bad experience to not plan future travel with United Cancún departure was delayed by 1h20 minutes, connection in Chicago was 1h30 minutes. Flight departure time 6:08 Miraculously 7 of us ran 4 kilometres through Chicago to arrive at 6:00 to be told very rudely by the 2 unprofessional United attendants you missed your flight and that we should of arrived early. Did I mention that reason I was flying? I received a call that my brother was dying and to get home. They provided no assistance would not answer any of our questions, ignorantly walked away. Deplorable

If United expects people to use their own devices for entertainment they should put charging outlets in each seating area. I arrived with 14%battery power. That is not good when you arrive anywhere and need to communicate for transportation.

Flight got delayed like 5.5 hours and the only compensation I got were 270 pesos which is nothing compared to the cost of a full meal at an airport or a hotel stay since the flight was during the night. No one seemed to know anything as of why the plane was delayed and I had a poor experience with the customer service line from the airline.

They miss placed a piece of luggage. My kids booster seat. How am I supposed to drive home with no booster seat?

With a business flight, having a designated seat in the aircraft, I was denied boarding at the gate at last minute without any genuine explanation. The staff used profane language when asked for reasons. Viva overbooked and passenger had to pay for it. The food voucher that was provided did not even cover the the full meal and water for a single person. It should not be running in service.

Super BAD Everyone Behind the counters in Cancun Not Helpful At All And then on the second flight I Had to purchase Cancun - Guadalajara one of the flight Attendants Kick Out a Couple Out of the Plane and that Flight Attendant Had a Mask So People wouldn’t take pics of her and she was kind of Mean ! I Would NEVER Flight VIVA EVER THEY ARE NOT FRIENDLY AT ALL ! People think They Are Cheap but They Arent!!!

It was cancelled at the last moment and the customer services seemed unnoticed to this change and hanged me off the phone the first time I called.

The boarding process was ridiculous. The boarded groups into a walkway just before the aerobridge (about 20 mins late), whilst we watch the crew stroll casually onto the plane, running late. And then they made us line up on then aerobridge with no aircon for 10 minutes before we boarded. Staff are just as ghetto as the customers. Wouldn’t fly again

They closed the gate over 25 minutes before departure and I didn’t get to board.

NOTHING.. THEY CANCEL MY FLIGHT WITHOUT NOTICE AND ENDED UP BUYING A NEW ONE..

Ridiculous fees for seats and restrictions of 10kg carry on. Cheap a$$ airline

Viva aerobús didn’t let me check in to my flight even when there was more than an hour before take off.

My seat was double sold, so It had to be sorted before I could board. No wifi entertainment, it was offline.

Hate it. They do not provide any food or drinks during the flight, unless you pay. They also charge a ton of money to bring a carry on bag. And their customer service is the worst. I will never fly with them again.

The money you save flying volaris is not worth it

Unfortunately it was not a good flight got canceled had to be at the airport all night long to get a different flight to another airport my first flight with Volaris was very bad. Poor services

The boarding , and it would be nice if they would let us know head of time about flight changes

In Mexico charges too much for my luggage and I ask for help and nothing one lady she just disappeared 😡😡😡😡😡never going to fly there

Better communication about delayed flight. I am thankful for a small credit for late flight.

Terrible. And they charged over $400 just for luggage. And threatened that I would loose my flight if I didn’t pay. So I didn’t have another choice but to pay.

I got to where I needed to go quickly. There were no amenities. And the seats were painful.

The flight was delayed an hour and a half, and they would not update the board on when the flight was supposed to take off. Once the plane arrived, they started the boarding process before the plane was even ready for the passengers so we had to wait another 45 minutes on the tarmac while we waited for the plane to be ready for us. In my opinion, there is no point in starting the boarding process when you are not ready to board the plane. This just causes a crowded gate with everyone from zone one and zone two standing up going nowhere.
