Great boarding, great short flight but no entertainment whatsoever and no wifi. Prepare to disembark by a staircase.

Great boarding, great short flight but no entertainment whatsoever and no wifi. Prepare to disembark by a staircase.

Transfer at CDG to connecting KLM flight to Amsterdam was a NIGHTMARE. LONG WALKWAYS, NO MOVING WALKWAYS, POOR signage, Have to take a train & No staff visible to help navigate the maze. AVOID TRANSFER AT CDG AT ALL COST.

Good food. Excellent crew service. Clean aircraft. Narrow seats and isle.

There was fog in Amsterdam so many flights were delayed because of the weather. Air France knew that the flight would be delayed by two hours but still boarded the plane on time. Instead of letting the passengers wait at the gate we were crammed into the plane. It was uncomfortable. No refreshments were given. I couldn’t charge my devices onboard.

I tried to upgrade to premium economy anis seat online during the checkin process. The payment didn’t work due to a technical glitch on KLM’s website. I wasn’t able to change my seat unless I called Amsterdam. Since I was in Canada and there’s a time difference this wasn’t practical. So when I arrived early to Ottawa airport my seat wasn’t available and I could only get a middle seat in premium economy which isn’t great. These middle seats are priced at the same rate as an aisle seat which makes no sense.

Seats were comfortable crew members support was very good but AVML ordered or selected by us needs a lot of improvement.

Transavia flight, was booked as KLM but i couldnt select seat or access boarding pass with KLM at all. Crammed seating and very no frills experience all around. First and last time.

Transavia flight. Couldn't select seat or anything prior to flight. No connection with klm systems. Seats are very crammed. Extremely no frills.

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

Flight left a few minutes late, but that's it. I wish the seats could be wider and recline more.
