The boarding process on the departure from LA was rather slow even though I was in Group 1. For first class, I was not expecting to have to pay for Wi-fi but I did and then the wi-fi was spotty. The entree was surprisingly good and so that was a pleasant surprise. However, once I got to Houston, it was terrible. Unfortunately there was bad weather but the constant gate changes for my connecting flight was difficult to manage due to having to navigate back and forth between different terminals.

The boarding process on the departure from LA was rather slow even though I was in Group 1. For first class, I was not expecting to have to pay for Wi-fi but I did and then the wi-fi was spotty. The entree was surprisingly good and so that was a pleasant surprise. However, once I got to Houston, it was terrible. Unfortunately there was bad weather but the constant gate changes for my connecting flight was difficult to manage due to having to navigate back and forth between different terminals.

The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

The flight was delayed, they didn’t even have water for the toilets or for drinks

Even through the flight was delayed due to storms near IAH The flight was great! The crew was so hospitable and professional

The flight had a delay but I made it to my connection. Flight was smooth overall

No screens or meal options. Freezing cold. Dirty seats. Left late.

Overall flight was ok. Flight attendant was receptive to assisting passengers with tight connections.

This was the first flight in the morning. We boarded fine. The cabin door was closed and we were ready to go. We were notified by the Captain that ATC issued and ground stop for 40 minutes. So, without even pushing back from the gate, we were already 40 minutes late. We actually were released to push-back and taxi at 30 minutes. But, some passengers had tight connections and were not going to make their connections. Some passengers asked about the delay and the effect on the connections and were told by the cabin attendant that all flights will be delayed and so they should be OK. However, that was not true. My connecting flight was on time and I arrived at IAH with 21 minutes to make my connection. I did and I'm happy about that, but the flight crew should not have given assurances to the passengers who might have missed their connections.

Boarding was again a "free for all". We were boarding group 4, and almost the entire plane was able to board before us. It's a shame that someone who follows the rules, gets the short end of the stick. Not fair.

The plane was so gross and dirty. Literally saw dust layering and flowing out the grey vents. Dust was all over the air vent knobs to the point where I took my sani wipe and cleaned them down so at least it wasn't blowing my my face. Also, I upgraded and paid for Wifi and it's always so spotty. I get we are in the air, but don't charge for it if it's not going to work. I expect so much more from United. They really are giving up.

When I wanted to check in 3 hours prior to boarding time, the employees mentioned “a little over an hour delay” so I waited for an hour then I went to go look for food in the terminal and most people from that flight were in the same area looking for food. Finally I decided after food to check to see if it’s anytime closer and now it’s 2 mins until boarding closes?! What are you kidding me? I didn’t receive anything via sms about boarding now nor via email or on the intercom. I luckily made it through, barely, and then there’s no room for my carry on mind you I’m in the very first row so I had to place my purse in one further row back and my carry on sections down. Not sure who pays for better seats to get your stuff placed all over the plane but that was the worst experience I’ve ever had flying with anyone.

baggage clamed had to wait over a hour and half for all people on my flight it was terrible

My flight was canceled I was promised a reginf still not received.

An absolutely fraudulent experience. Extremely unprofessional. Terrible in all ways possible. Rude staff, flight attendants, and deceptive "policies."

The worst service , the agents from the counter are really bad . Poor customer service . They didnt help me to get in the flight . I was on line when they close the flight without telling and I couldn’t board the plane . I will like to get my money back ey back because it was their fault. Really bad management , bad manners, bad additud

My first flight was moved 6 hours causing me to miss my meeting. The second was delayed about an hour and a half. Most of the crews apparently dont like their jobs or just working for Frontier. Only one flight attendant wasn"t snappy or rude.

First time experience and though you'll pay for *everything* meaning bags, water/snacks, even a question with a service agent - - all in all, not a bad experience whatsoever.

I fly Frontier often and generally don't have any issues. For some reason, the Denver to Houston's George Bush Intercontinental (IAH) flight always needs to wait on the tarmac in Houston because a gate is not available after landing. I've been stuck for as little as 15 minutes and as much as a little over an hour. I know only fly the Frontier Denver to IAH route when there is not an available flight to Houston Hobby (HOU).

Terrible Y lost my connection to Mexico, nobody of your company help me And y pay a lot of money for my baggage Until now I continue in the Houston airport I vneed you return my money

I like the easy check-in and boarding process. I love the non stop flight
