Premium economy was great. Plenty of leg & elbow room. Delicious food.

DO NOT book with Kayak or a third party travel agent like Underpricers. You will regret it.

I have flown over 2million miles. Great flight but bizarre boarding process. They must have paged half the passengers to the desk for documentation check before boarding anyone. Overall great value.

The flight itself was pleasant and on time. Crew was very good. However, breakfast food was barely acceptable. Unfortunately this satisfies the recent industry standards. I asked for a sandwich with ham (another choice was cheese), but received a sandwich with roast beef.

Agents helping disable person doesnt know connections to Poland and after 9 agents helping and 2hours ,we made it to proper terminal. Polish Dreamliner its Polish nightmare liner with so narrow seats and no room under front seat for bag and feet,in economy class.To upgrade, to higher standart cost an arm and leg ,even there are empty seats No good experience overall

Boarding was impossible to navigate. Had mobility issues and a business class ticket, but still boarded almost at the end of the queue because there was absolutely no organization or assistance.

LOT was very disorganized at Istanbul airport with no communication with travelers. Our flight was delayed over and hour and a half and there were no announcements, displays or anything about it. It almost left me missing my second flight!

The flight was delayed by an hour which caused me to lose my car rental in Vilnius

Lost my suitcase. And communication was poor. No offers of compensation for over 24 hour delay of bag

My flight was cancelled and I went through hell to get it fixed, with no help from the website I booked it on. My reservation was cancelled AGAIN by the site I booked on without my knowledge a week later. The flight itself that I finally got on was awful. Drunk man belligerent the entire flight, I don't understand how he was allowed on the flight.

Turkish Airlines made a long flight from YVR to IST a great flying experience. From the attendants, to the food, to the entertainment program to all the extras, a twelve hour flight ‘flew by’. Late departure and arrival was not the airline’s fault.

Boarded via bus instead of the air bridge Had to wait 10mins in the bus at the tarmac before we were allow to go up

The flight attendants were great! The seating for business class is better on other airlines. The food was also good!

Great food, great entertainment and very helpful, caring & attentive staff.

Food is getting worse. They use to be different than other airlines. Their economy classes food sucks. Stuff was very helpful.

Horrible, they forgot our luggage, the food was terrible, the crew were rude, the flight was delayed, I hated every aspect of this flight

The flight was delayed so connection was missed. In Istanbul we were taken to a hotel and no one in the hotel knew so we had to wait hours in the lobby of the hotel while the airline and hotel coordinated. The airline staff is rude at times

The checking line was very long , when checked the bags and got the boarding pass but moved fairly fast . The boarding line was long and the ground crew didn’t provide priority to kids boarding . But the air crew on the plane were very nice and polite . Too bad my daughter’s table try was broken which made the trip less enjoyable.

Food could have been hotter. More padding needed in economy seats

Was not able to check in online, so had to stand in line for 90 minutes to get a boarding pass, and I had no luggage to check. Why not let people check in in advance on line? Or at a kiosk at the airport?

The crew were very friendly and made me feel at home. They should give us food not snacks especially when traveling with an early plane. I think breakfast will be appreciated

No problems other than no seat back entertainment. Everyone was very pleasant

1st time using air Canada. We were a little delayed waiting for a new plane that did alter our plans for the evening but it was handled as best as possible. Everyone was pleasant.

It was our first time flying wit Air Canada. I found most everything very good, however, our flights leaving and returning were both delayed. And we were met with no place to de-board the plane and had to wait an additional 45 minutes on the plane after arrival. That was very disappointing. Also hefty fees both ways on what would normally be a carry on bag on any other airline.

Like the crew, the wifi set up was a trip. Might have been my device though

Too hot. Air from vents not working Long line for toilets Not enough staff to offer water throughout the flight

So cold. Too cold to sleep. Too cold to get comfortable. Wearing boots and a jacket and still so cold that I would need to curl up if a plane actually had enough room to allow me to do that. Miserable.

After we boarded, we sat on the tarmac at least a half hour. Not that big a deal really but kept me from giving the survey an excellent.

Traveling from Montreal to SFO, after landing in SFO, there was no announcement about where to claim our luggages. Our gate was in Terminal 1, and went to the luggage claim area in T1, but couldn't find any information on the screen. Eventually, an airport agent told us that our luggages would arrive in Terminal 2 luggage claim area.

Everything was excellent. I had lost my ID card and the flight attendant found it for me.

Everything was good except the seats we originally picked we did not get when we paid for extra leg room. Had to wait till last minute to get assigned our seats which was nerve racking

In business on the top-deck of an overnight transatlantic flight. A family with uncontrolled young children were there too. All night they were running around up and down the walkway while squealing . . .

Boarding was weird. They boarded two flights at the same gate at the same time. So mass confusion for the non English/French speakers. So many people at such a small gate. Like every other part of this airport you have to walk miles between everything. Gate to plane was a 5 min walk :) several long flights so I was worried about my steps but ended up walking several miles here so worked out.

I never got to Lufthansa because of Air Canadas negligence.

The flight got delayed 3 hours from Montreal and we missed our connecting flight so it was a long journey

The agent, who took my mother to her gate, kept talking with one of her male coworkers and treating my mother like a sack of potatoes. She was ignoring my questions because she was too busy flirting with her male colleague. This was a very unprofessional behavior. We also had to wait for close to half an hour for an agent to arrive.

Very good flight, only problem is the boarding process where some peoples do not have manners and do not how to fly ( preparing your documents, oversized carry-ons, not understanding or feigning to not understand directives).

I really like it and travel to Europe and back with Lufthansa, but it is getting expensive, a bit beyond my me

Not available crew to load the luggage for all the passengers,comon situation for local European destinations , not acceptable situation, never Lufthansa again 😉 🙄

Flight was overbooked. Crew did a great job but passengers weren’t nice and really not patient. Flying in these times is not the best idea tbh.

I didn't like the food, and it wasn't as good as all other business class that I'm using

I'm flying several times per month in business class. You had the worst food by far from any company I have ever flew with. The Spanish wine was great. I purchased Internet, but it didn't work well for most of the flight.

All good, professional service, and arrived close to on time.

This was a special trip so we booked first class. It was obviously an old plane as the seats weren't that comfortable or spacious. We were delayed 45mins taking off as the "little engine that starts the big engines doesn't work". The powered divider between myself and the next seat in first class didn't work and my electrically powdered seat didn't work so I had to move seats to try and get some sleep. Food and drink were good, crew were great. But I'll never fly with BA again.

Need thicker and wider blankets. Food was below standard especially in the fist leg.

The onboard service makes it extremely difficult and slow to go to the toilet

The boarding process was a disaster. No one respects the boarding groups—tired old aeroplane. There are no sockets to charge phones. The cushion seats are ancient and hurts back and gluts

Amazing crew - they were exceptionally nice. From ground staff to the plane

Small overcrowded flight with limited overhead storage bins. The last row 30 has no windows. The aircraft has no entertainment system. The flight is 3+ hrs and is not a low-cost, but the free snack is a laughable size: a SINGLE bite soft cake/pie.

The seats were quite uncomfortable. I felt like I was leaning forward the entire time, which was quite bad for my neck.
