Oh the crew was very pretty. They spent more time on themselves their hair their make up and on their phones than they did the entire first class. Check our flights and miles. We fly AA ALOT for ourselves and other. WCB4350 Shipman. We don’t complain ever. But when you spend what we do and only just get your first drink with your dinner in the air is utterly ridiculous. Never got a clean up or a second drink. Had to interrupt the glam squad from their phones and make up bringing them our dirty glasses and trash asking for a second drink. Not impressed with this crew at all! Normally AA IS TOP KNOTCH. So it sets the standard that we’ve been accustomed to however complete and total letdown on this flight

It was a crowded flight home, I knew that when I checked in online. I was forced to check my bag plane-side...to be picked up at baggage claim upon our arrival. Inconvenient to say the least. The crew announced there was in-flight wi-fi {available for purchase, of course} only to come back on and apologize that the wi-fi was down for this flight. The crew did do beverage service, but never made it to the last three rows of passengers. Overall, just not the type of customer service I am used to from other airlines. I chose this flight based on the price. I don't think I'll chose United again in the near future.

I received my e boarding pass the night before

The boarding pass that was sent the night before had the incorrect gate and no seat assignment. I spoke w THREE agents at checkin and they all sent me to the (wrong) gate- C25 and wouldn't give me a seat assignment. That is a long way to go w a scooter and a bag, only to learn the correct gate is B4. I was the last to board, there was no bin space left. it shouldn't be so complicated.

I had to cancel my flight because I did not want to miss my daughters baptism. I did not know the date of her baptism when I booked the flight. When I I tried to change the flight it would have cost twice as much. I’ve always loved flying with Spirit. Until this time. When I asked if I could get a travel voucher for a future date I was told it was a promotion so I could only get a $10 credit even though the price I paid was $120. I’m so sad.

Finnair flight AY06 are old aircrafts. Every other in-seat monitor was out of order, flight attendants could not do much. That created mess for passengers, trying to move their seats to the ones with working monitors.....

I like that two checked in bags are included in the price. ISP is close to my home and easy to get in and out of. The airline is always on time, even when there is a late departure.

The seats have changed. They are narrower in width, the knee room is less, the staff while still professional is more serious, not as fun and friendly. Spicy snacks and peanuts are limited. Cookies go better with tea and coffee on the late night flights.

Plane arrived early and deplaned early. Crew pushed to serve drinks even though there were bumpy stretches.

In boarding, putting groups 3, 4, and 5 in the same line works poorly. The size limits on carry-on bags and personal items was smaller than other airlines, unnecessarily so for the latter given the size of the space under the seat in front. United is inconveniencing customers without any justification.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.
