At the airport I was a mess and the airline counter attendant was so amazing helping me ( I had never flown United and had no idea about their luggage policies ect..). She quickly pulled me aside.. helped me with checking in and did her best to fine me another seat thatvwas better than the one I had already chosen.Also, she gave me a hug and her condolences. Flying with an airline that has heart helped me so much during one of the most difficult times of my life. I will absolutely fly with them again."
Cons: "No complaints ... but I paid for a movie to take my mind off of my father's passing during the flight and there was a short in my monitor for our whole row.

Pros: "Landing safely."
Cons: "Everything else. I flew from PHL to IAH and was very unhappy with the experience. The gate agents were unfriendly. The bag check agents downstairs were unfriendly. I had two separate phone calls with United a week prior to the flight to understand and confirm the bag policy. This was AFTER booking my flight so they knew upfront I bought a basic economy ticket. After my first call, I understood a personal item would be free and I would be able to pay for my carry on bag, but only within 24 hours prior to the flight. I made a second call to be absolutely sure the previous agent gave me the correct information and pricing. So I paid the $25 for my carry on, checked in online, and waited at the gate while boarding at the very end because I was basic economy. They did not let me board with my bag. They requested another $50 to check my carry on with them or I would be rebooked. I struggled to afford the flight, let alone the carry on fee I had paid in advance. I literally did not have the money, and even if I had the cash, they only accept plastic. What blew me away was they weren't asking me to check my carry on because of the size. But because of my basic economy ticket, aka, the N fare. Despite checking with two employees by phone after buying my ticket and paying for a carry on in advance, there is a rule in place that states "if you have purchased Basic Economy, you will only be allowed one personal item, unless you are a Premier member or a primary card member using a qualifying MileagePlus credit card." Therefore, there is no alternative. You are a second class citizen; a no good deplorable, when you buy this ticket and there is nothing you can do to upgrade it. Only the "premier" passengers have the right to bring a carry on aboard even if you think you're paying for the privelage. What I was expected to somehow understand after asking two United employees prior if I could purchase the right to bring a carry on bag aboard, was to CHECK my CARRY ON downstairs or learn the hard way. Wow. What a ruthless way to learn this lesson. I waited 7 more hours to board the next available flight. What a nightmare. I thought I had did the appropriate research necessary and planned in advance to avoid these situations. Checking in online and contacting customer service prior is no longer the convenience it used to be. Even if you've done your research, bring additional funds with you. Even if you check in online and have a digital boarding pass, always check in with a real human prior to entering the TSA security line. A side note, United is trying to save money while "speeding up" the process by forcing you to use a computer to hand over your checked luggage. Speaking with a human now is a monumental struggle."

Pros: "It had movie screens quite old but better than none"

Pros: "From check-in to touchdown, my travel over this Christmas was awesome! Flights were on time, security ran smoothly, and I would use Kayak again for sure."

Cons: "Hour late taking off and customer service terribleness!"

Pros: "No issues ELP to HOU"

Cons: "Having to pay for luggage, drinks n snacks"

Cons: "$60 for a carry on?"

Pros: "I think this airline should be a little more open about what's going on. Upon booking, no mention of baggage fees. There was a delay that we knew nothing about as we sat there. The crew wasn't very welcoming. Probably wouldn't book Frontier again."

Pros: "The luggage policy must have been informed to passangers prior to the purchase of the ticket. I am unhappy about the fact that I could not carry my small luggage as I used to."

Pros: "I was easliy checked in"
Cons: "It was more then an hr late The plabe shook all the ride long It felt terribly unstable"

Cons: "The cabin crew can be a bit more friendly. There were several exit-row seats empty and I saw they asked somebody to leave one of those who swapped seats during the flight. If this is the company's policy, they can announce it in the beginning which would make things easier."

Pros: "Everyone were really nice. The service was good."
Cons: "I didn't like the following fact. I was charged $35.00 for a carrying on bag. When the bag met all the requirements needed for a carry on. When other customers had larger bag and they were not charged. The bag was small enough to fit under the seat. I should be re-enburse the $35.00 I was charged. Thank you"

Cons: "Delayed with no information given. No charger ports."

Cons: "The delay"

Cons: "I feel that Frontier baited me with competitive fares when booking the ticket. When it was time to print my boarding pass, there were extra and excessive fees that other airlines don't charge and weren't disclosed at booking. Frontier charges a "seat fee" just for selecting a seat for the flight. They charge a "carry on" fee for a carry on bag. When added to the booking fare, the total cost exceeded what I would have paid on another airline. I feel tricked and deceived. I would not use Frontier again unless they were the only provider."

Cons: "Charged extra $60 for check-in baggage for the round trip. The baggage was 25lbs and there was a carry-on option, but charges showed $70 for that during on-line check-in. The boarding crew in Philadelphia were excellent, but the same things cannot be said about the ones in Houston. They were rude in their reply to questions. The return flight was delayed by 45 mins. The baggage claim was horrible. The baggage carousel was jammed and it took another 45 mins to collect the baggage. Overall mediocre experience!"
