Perfect flight. Smooth flight. Arrived 20 minutes early at destination. Excellent service.
Perfect flight. Smooth flight. Arrived 20 minutes early at destination. Excellent service.
The flights were on time which was great give. It was holiday travel season and there’d been some weather issues. The only complaint and this is every time with United is the terrible seat design. The head rest is not built for comfort and having my neck bent forward for a cross country trip reminded me while I try not to take United flights as a rule.
Everything was absolutely wonderful from check in to baggage claim. Staff was very professional and sweet. Will definitely recommend United to family and friends.
They did the one thing that really matters - got to Chicago early.
The flight was on time. I generally don’t drink or eat on short flights and the seats were good and the flight attendants were friendly. That’s all I expect
It was nice to have gotten up upgraded to first class with a meal on a three hour flight
Very bad! They kept delaying my flight and wouldn’t do anything about it
Door to door, the crew and staff were amazing. It was a stressful travel day with delays, but they were focused on customers and doing what they could to get us to our destinations.
Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.
Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.
Little warm on the plane and delayed for an hour
So excited very proud first of all I wanna thank kayak all updates very professional and fast alart And amazing cabin crew so nice to me they deserve big salute
The boarding process needs to be fixed. The zone don't work, especially when there is hardly anyone in zones 3, 4,and 5, leaving the majority of the passengers backed up in the aisle, especially because passengers seated near the front are blocking passengers who are seated in the rear of the plane. It would also help if the size of carry on bags was more strictly enforced.
Awful. They won’t help me with anything. I booked on American but they abdicated to Iberia. The ticket was overpriced. Everything negative
I enjoyed the extra leg room compared to other airlines. The first stewards made my daughter’s birthday special by giving her an extra snack. Then the last one coming home from Chicago to Appleton made our night really enjoyable Thanks for making our trip enjoyable
It was good..clean, comfy seat. Friendly warm welcoming crew. Was able to check my cabin luggage at the gate which I was able to pickup in a decent time from baggage claim. The app gave all updates from delays to baggage claim info. Overall smooth flight.
It was a typical flight. We had a delay which seems to be the normality now. And we had no in flight service due to conditions.
After we landed we sat on the tarmac for 1.5 hours waiting to get to our gate. Ridiculous.
Terrible. Flight delayed for more than 8 hours with only a $12 meal voucher provided for the inconvenience. The airplane did not have breaks on arrival yet they still made us go through the motions and board on time knowing we could not take off then sit for 40+ minutes before having to get of the time. A complete waste of my time. I cannot believe they can stay business with these shenanigans. I’ll avoid this company like the plague moving forward as the lack of accountability is disgraceful.
This was the best 2 flights I have had with American out of SGF. Great crew both flights.
The flights were very uncomfortable the seats don't have much leg room at all and they are pretty hard as well.
Our outgoing flight was cancelled two hours before boarding and Spirit was not able to get us onto another flight. Their customer service was slow and unhelpful.
spirit delayed my first flight 9 hours and then cancelled my flight back home. Very disappointed with their service.
Sprit being a value airlines providing flights for less prices, does its basic job. Flight was on time and ride was comfortable. Its did take off and landed on time. Luggage took sometime to arrive at carousal but that could be Newark airport issue.
Worst every experience travelling with Family. So much delayed while going and returning both. All airlines were time except this. not sure Spirit operational issues. No recommend Spirit. It may spoil your entire trip. Rather spent extra $ and book better airlines.
Late taking off. ATC sent us circling around Chicago for almost an hour, after landing taxied for 40 minutes.
Canceled flight without any explanation at last moment. No replacement options. Not a weather related event. Completely messed up our holiday plans.
I waited for 4+ extra hours to even board when i was fighting off a cold. So i was sitting there in the airport with a fever and chills while spirit wasted my time. Then once on the plane we had at least an extra hour of taxiing before and after takeoff. Really poor airline, no amenities to speak of, and a lack of organization that will just ruin your experience.
Terrible. They cancelled the flight at the last minute after I had checked in at the airport and then told me they could only put me on a flight after 7 days. Pathetic.
Flight was on time. Friendly crew. Gate agents in the other hand were very unfriendly.
It didn’t happen. I booked it and then was told it wasn’t available and then forced to pay far higher prices for a worse option
This company socks. It's fraud. They canceled our flight yesterday, and today we were late because of a really long line at the check in bag. At the rebook station, there was ton of people. The workers were all rude. I am gonna make a report to FTC.
Flight got delayed for 5 hours no good explanation was offered ;(
There was no one at the counter to assist with our check in. The app didn’t work, so I arrived at the airport with time to check in and I couldn’t because no employees were there. When I finally got someone on the phone, it was inside the 60min rule and they said I could no longer check in and they could sell me another ticket. We had to scramble and pay an additional $800 for tickets and THEN AFTER (about 60 min from my original convo with customer service and 10min after original departure time) I had boarded my new flight, there was email saying my original flight from Frontier was delayed and leaving 2hr 50min later, but I STILL wouldn’t have been able to check in. Which means customer service should have been able to see it and let me check in because I was well within my check in time. When I call Frontier, they hang up on me. So their app didn’t work and they employees left and they take zero responsibility or assistance with their “customer service”
The single worst check in experience I could imagine. I’ll never do any business with Frontier or any affiliated company
Too many extra fees, uncomfortable, little leg room. Will not recommend this airline.
Everyone seemed to be in zone 1 for boarding. Maybe break it up a little. Otherwise, smooth flight.
The experience was good. No frills but I got there safe and sound and on time.
After boarding and un-boarding twice over 6+hours, the flight was canceled.
Severe turbulence. Captain never came on to reassure passengers after things settled down.
