Crew was nice. Flight very smooth

We had to get seats at boarding because of the flight delay. She offered us two seats in the back. I knew they don't pushback so I said no. She had given the woman ahead of me two seats in comfort plus. Did not offer that and was rude. There were at least a few empty seats in that area. As a courtesy to us having 1)been delayed in Costa Rica. And then 2) a long wait for the connecting flight in Atlanta it would have been reasonable to offer those seats. Which remained empty

The free in-flight entertainment was great. I appreciate it being free as it makes up for some of the other issues of not being able to sit next to fellow travelers on the low-fare

Did not like that on the low-fare I could not choose a seat next to my traveler. This made me ask the person next to my wife if they would like to switch, which they nicely did. But I imagine this asking of switching seats will probably create tension for your customers in the future. You might consider going back to the original model of sitting next to your fellow travelers.

I flew economy. We left the gate on time, the seat was comfortable, entertainment was varied, flight attendants that I came in contact with were professional and pleasant, food was hot and very good, pilots got me where I wanted to go, and that little container of ice cream - oh I love it! The plane was not completely full, which made the seating more comfortable than it would have been if the plane was full.

I was ushered into what became a very slow line to board. The employee at the end of my line had to deal with a few problems so I ended up boarding close to the end, behind those with higher group boarding numbers than I. Having a single line up to the two boarding employees, would avoid that, albeit make a longer line to begin with.

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.

We compile tonnes of data for you
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.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
