Pros: Smooth flight

HEL
TKU
Mediocre 3.0

Pros: At least the crew was friendly

Cons: The flight was delayed for 1 hour and we were sitting inside the airbus with no air condition due to technical difficulties on 35 degrees sweating like pigs. No water or snack was offered even though the delay was so big.

YYZ
LHR
Mediocre 2.8

Pros: There wasn’t much to like. One of the crew members stood out by being helpful; his colleagues were bureaucratic and disengaged.

Cons: This was a BA flight. Food in T3 in toronto was a disgrace, and the whole lounge experience was poor. The sleeping arrangements in business class had no privacy; the food onboard was mediocre. The Air CANADA flight on the same route is far better in every respect.

I talked to an agent and they told us we would have to pick up our bags at a different carousel and then go to the ticketing agent for a new flight. 1 ticketing agent+3 hours of waiting = 1 pissed off traveler.

Pros: Fell asleep and didn’t even realise. Finnair is very friendly and the staff are super nice. I was very thirsty and asked for two cups of water instead of one and the lady was not hesitant to give me two cups in quick succession. Very good air company

Cons: Nothing really too bad, you get what you expected. May of been nice to have a free sandwich as it’s a non stop flight - this is because Lufthansa has one stopover and offers a free sandwich and drink.

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

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 prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons 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 don't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires 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.
