Passenger Reports

Did Casablanca to London last January and it was genuinely one of the smoothest long-haul flights I've had. Barely any movement the whole way.

Frequent flyer · January

Totally smooth April flight. The seatbelt sign came on once briefly over the mountains but nothing actually happened. Great trip.

Leisure traveler · April

Was nervous about this flight but honestly didn't need to be. Smooth the whole way, the 3h 20m went by fast.
