The seats were clean; the cabin looked very nice. The plane got me from point A to B safely. smoothest Lansing ever!

Flight was delayed 2.5 hours. No communication from the cockpit, 2 out of the 4 flight attendants we really crabby. Undersea storage was unusually small. I’m 5’8” and my knees were pressed against the seat in front of me and the seats are hard. My legs were numb for part of the trip.

The scheduled plane had a mechanical problem so we deplaned for alternative plan. It took six long hours to get another plane in. Meantime passengers stood in line for hours to make other arrangements. It would have been appropriate for the airline to call in extra staff to help stranded passengers. We missed the scheduled connecting flight and a tour. We got in at 1:00 am, 12 hours later than planned. We had meetings next day and were very tired because we got in so late

Considerate flight attendants. Turned lights down for evening flight, so we could get some rest.

Flight was not on time. Time was changed a day prior with no reason explained. No in flight entertainment on this flight.

We arrived on time.

These planes feel like they are made of Legos. They are absurdly tiny and uncomfortable (and I am a small woman). Hot and stinky when boarding and no room for you or your carry on luggage. The days of glamorous air travel seem very far away.

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,
