Pros: Very helpful and courteous flight attendants; low fare; ability to reserve a seat when ticket was purchased. Leg room was good.

Cons: No procedure for boarding except to have everyone pile up in one mass. The staff at the gate seemed irritated that we had not had our boarding passes clearer at the counter, even though we had no bags to check and the boarding pass directed us to go directly to the gate if no checked bags. We had to stand aside while the inpatient staff cleared us. Naturally as more passengers went ahead, we had to search hard for a place to stow our carryons.

Cons: The entertainment system didn’t work well to start, and then stopped working altogether 2 hours into a 5hr flight. The staff tried to fix it and were very apologetic, which made up for it. The seats were a little too hard for me. I was pretty sore by the end of the trip.

Mediocre 2.0

Cons: I used Kayak to find my ticket and fill out my information (all kayak logos on top of the page and so on). However, when my confirmation email and e-ticket came in, they were issued by Budgetair.com. I had no experience with them and took it to be a reliable website since they were working with Kayak. However, I had to change/cancel my flight because of delayed passport delivery, and this is when everything turned very Ugly! I had to spend an hour over the phone to get connected to an agent with BudgetAir, who disconnected the line within 2 minutes saying: “please hold so I can pull up your information”. This game went on for 6 hours. I tried to connect with the airline directly to make the change, which was not possible since Budgetair had placed a restriction on this ticket. After 6-7 hours, which meant no work for me or lunch because I was sitting behind my desk with a phone on my hand, I got through an agent who was rude and impolite. He took 15 minutes to find flights for the new dates (I did it in 2 minutes on their website), and then told me to pay $315 in extra fess. When I inquired that the prices on your website for the exact same ticket is way cheaper than my original ticket price, he got angry and aggressive. Basically implying that I have no choice to take their offer as is, or let go of my original ticket price of over $2000. Long story short, DO NOT buy from BudgetAir if you like having a peace of mind!

Attendants are more friendly and loading is more organized. Way to go Delta.

Pros: Everything that happened during the flight was fine. The service, the flight itself, and the landing – which was excellent.

Cons: On the ground, neither the staff nor the signage made it clear exactly where to check in. I was sent to the Lufthansa counter, which didn’t open until 11:30, when I should have gone to the United counter. An hour of my time was wasted, which almost resulted in my missing the one-hour before take-off check-in deadline. The only reason I didn’t miss the deadline was because the flight was late taking off.

This unfortunate situation has influenced this review greatly particularly because this wasn’t a 2 hour flight but a long haul one.

Pros: I last traveled on British Airways in May of last year (2015) and the food was beyond dreadful. Therefore I was very pleasantly surprised that there has been a huge improvement. They were very generous with the drinks and the food was plentiful and quite a reasonable standard for airline food (they gave two full meals from San Francisco to London, whereas most airlines give one meal and one snack on that route). They actually checked us in on the earlier side, we took off very promptly and got to London early. It was nice to be on time for a change - so often I find airlines run a bit late. Staff were all pleasant and helpful. Pilot's messages were pleasant, friendly and even a bit informative.

Cons: Web check-in ahead of time was a total disaster. I got an email telling me I could check in 36 hours early and "secure a good seat" but neither of the 2 sets of codes they provided in the email would work because it was all about Finnair but actually the flight was being run by British Airways. I spent about 30 minutes on the 'phone trying to get the appropriate sequence of numbers and letters to enter so as to check in and get a good seat - still nothing worked. This was at 5:45am - I regretted the time spent when I could have gone back to sleep. My daughter later spent a further 90 minutes trying to figure it out, only to be told finally that our only option was to get to the airport early and check n there which was what we did. It was beyond irksome. Please note, if the airline actually flying is different fro the booking airline, the locator number for check n will be DIFFERENT and needs to be provided to the customer to avoid a great deal of hassle and confusion. We gt particularly unlucky because BA computers had a glitch that day but the general point still stands.

Pros: Very helpful and courteous flight attendants; low fare; ability to reserve a seat when ticket was purchased. Leg room was good.

Cons: No procedure for boarding except to have everyone pile up in one mass. The staff at the gate seemed irritated that we had not had our boarding passes clearer at the counter, even though we had no bags to check and the boarding pass directed us to go directly to the gate if no checked bags. We had to stand aside while the inpatient staff cleared us. Naturally as more passengers went ahead, we had to search hard for a place to stow our carryons.

Okay 5.3

Pros: Did not realize I purchased a “no checked bag” fare - and the $60 each way charge really pissed me off, along with the &48 charge to guarantee a window seat again, each way. The site was misleading, and I resent being peneluzed for trying to be efficient. A two week work trip needs to include a checked bag.

Cons: For a new plane, seats are very cramped. If you drop an earpiece on the floor, you pull a muscle to retrieve it / or make. Everyone in your row stand up. Decent movies mean a box under the seat cuts into legroom. A cramped, miserable 7 hours for this 6’0 tall American. Staff was as helpful as they could be, but my knees still hurt.

Excellent 8.0

Pros: The plane and it’s crew were fantastic! The crew was totally customer oriented and provided great service for the entire flight.

Cons: It does no good to upgrade to Saga Class when you consider loading at Keflavik. A mob is herded on to a crowded bus and you wait at plane side with little room to move around. There is no priority boarding and the entire procedure might be acceptable in the Third World but certainly not in a country that has so much going for it.

Okay 5.3

Pros: It was relatively inexpensive. I didn't mind the food/

Cons: This flight was operated by BA. Seats were incredibly uncomfortable. When the guy in front of me reclined his head was practically in my lap. TV's were crappy and the in-flight selection was mediocre. In flights announcements were very loud through headphones.

Pros: I last traveled on British Airways in May of last year (2015) and the food was beyond dreadful. Therefore I was very pleasantly surprised that there has been a huge improvement. They were very generous with the drinks and the food was plentiful and quite a reasonable standard for airline food (they gave two full meals from San Francisco to London, whereas most airlines give one meal and one snack on that route). They actually checked us in on the earlier side, we took off very promptly and got to London early. It was nice to be on time for a change - so often I find airlines run a bit late. Staff were all pleasant and helpful. Pilot's messages were pleasant, friendly and even a bit informative.

Cons: Web check-in ahead of time was a total disaster. I got an email telling me I could check in 36 hours early and "secure a good seat" but neither of the 2 sets of codes they provided in the email would work because it was all about Finnair but actually the flight was being run by British Airways. I spent about 30 minutes on the 'phone trying to get the appropriate sequence of numbers and letters to enter so as to check in and get a good seat - still nothing worked. This was at 5:45am - I regretted the time spent when I could have gone back to sleep. My daughter later spent a further 90 minutes trying to figure it out, only to be told finally that our only option was to get to the airport early and check n there which was what we did. It was beyond irksome. Please note, if the airline actually flying is different fro the booking airline, the locator number for check n will be DIFFERENT and needs to be provided to the customer to avoid a great deal of hassle and confusion. We gt particularly unlucky because BA computers had a glitch that day but the general point still stands.

Good 6.0

Pros: Finnair cabin/seats, clean, quiet and comfortable airport in Helsinki

Cons: Not only the first flight got delayed for over 2 hours. I had to re-book the second - connecting - flight because of that. Now it made my layover instead of 1 h 45 m - 5 hours! Then the second flight got delayed!! So instead of 5 hours layover it was over 7 hours!!! Very inconvenient and upsetting experience. The only reason I booked these particular flights is because they were advertized as "the shortest trip" time on your website...

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.
