Food was Good, flight was without much stress and a little faster to compensate for the delay.

Delayed boarding, no announcements, long wait in line for boarding, repeated delays. Not the first time - Every tome I use this flight it is delayed and without clear information to passengers how much delay is anticipated. Announcements, even if they come - come not loud, simultaneous with other announcements - so impossible to hear. Scheduled gate is moved every time too.

He missed it due to having a 32 minute layover, which he ran all the way to board.

he had no choice but to look at the closed door of his flight, and wait an additional 7 hours and they didn't even give him a voucher for food. I'm his mother, I'm currently visiting family in Scotland, so couldn't help him much. I'm pretty disgusting and disappointed by the whole experience.

This is the second time your plans have been late! You were late leaving from Venice to London Heathrow on August 1 which I barely made the flight to Glasgow and then coming back your flight is late leaving Edinburgh to Heathrow And my luggage doesn't make it again! You don't even serve water on the airplane which is ridiculous! Your flight crew were nice but you really need to be on time or not schedule flights with such short layover times! And I hope no one takes anything out of my suitcase! And I'm sure nothing will be done so why do you even do a survey?

We are guessing they either overbooked or they didn't have sufficient passengers on a Tuesday afternoon who's final stop was Glasgow. They rebooked him for 1200 the next day. DFW to MN, St Paul to Schipole, Amsterdam to final destination, Glasgow. So he ends up having to pay for another Lyft back to our apartment in Dallas, then another additional one for the 12 noon flight the next morning. If he didn't have family living in Dallas, he would've incurred a hotel fee too.

He was bumped to the next day due to his flight being cancelled. Then re-booked the next day, with an additional layover. Then due to a 32 minute layover that left 3 minutes sooner...

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.
