Just a little improvement on food but everything is excellent

Just a little improvement on food but everything is excellent

We stood for a long time beyond the gate before any boarding occurred. Other than that, it was fine. It helped that it wasn't a full plane.

Like- beer/wine for free Dis-like- all other aspects- customer service was horrible the entire trip. No help from Air Canada after they changed flight 6+ hours later. Also they put us on standby for no reason. Then almost 2 hours to get our bags after we arrived back at airport

Flight was delayed but the real issue is how long we sat after boarding. Space very limited for an overnight flight and seatbacks didn’t recline so it was almost impossible to sleep.

The staff made sure I was comfortable, moved me to a better seat with more leg room

This was actually a bus ride to the KW airport. It was smooth and comfortable and on time.

The plane in use lacked an entertainment system (perhaps because it was still being updated?). It was an overnight flight so it wasn't terrible but still. The actual seat was adequate but not great. As an economy flyer, food review is largely irrelevant. I am unhappy with this race to the bottom for services provided especially as it applies to baggage restrictions.

Service Director cut all cabin lights and window screens defaulted to dark, but it was an afternoon flight going west. I spent hours trying to see what was reading as reading lights weren't working either. What the hell.

Enjoyed the flights with Air Canada. Friendly, courteous staff and flight crew - kept us informed and efficiently got us boarded and to destination on time. Seats were reasonably comfortable and good room in the overhead spaces.

The food could have been better. The flight attendant was the friendliest and most helpful I have ever had.

Hard to use tables and TV screens interfere with the enjoyment of flight experience. Other than that it was a smooth and comfortable ride and we were well taken care of.

Excellent flight overall. Lufthansa Business service was excellent with great cabin crew and very good food and wines. The seat comfort was excellent. Only a slight reduction in score due to the 747-400 being a relatively loud aircraft these days.

The flight was delayed by an hour. Made the connection uncomfortably tight.

When we went to the lounge they told us to go into the main lounge and not the full business class section, later they told me that Lufthansa wont pay the full fee to alloq the business class passengers entry to the nicer sectikn where all the other airlines nusiness class passengers go into. Very poor arrangement.

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

The flight was ok, the flight attendants were lovely, the movies were good, the food was ok, and I am just sad because my luggage didn't arrive with me in Iasi because the flight from Vancouver to Frankfurt was delayed and then I barely made the rest of my flights. Also, there was no real support once I got off each of the flights. There was nobody to ask about gate or where to be and for example when I got off in Vienna to catch the flight to Iasi there was no screen where I could read the gate and time of departure of the plane. I was going crazy trying to find the plane to Iasi and I barely made it. When my luggage finally arrived home it was broken. The handle was completely broken and that was not so good. I am in a visit here, in Romania, and I will have to buy a new luggage.

Crew were friendly and very helpful Plane was clean and the legroom is standard. Overall a good flight, no complaints.

The connection to LYON was very tight. The flight was nearly finished boarding when we got to the gate

The flight crew, the on-plane service, and the food were fine. The seats lacked cushioning and were uncomfortable compared to other planes from recent flights. The plane was initially delayed one hour and that expanded to 1.5 hours. When we boarded, there was insufficient room for our carry-on bags, which added more time to disembarking from the plane. It appeared the Air Canada staff or the Toronto Airport staff were less than competent to handle whatever the issue was that caused the delays, which was never communicated.
