I’ve had 6 A330 flights in the last 10 days and 5 of the 6 had WiFi.
Given it was free and unlimited it worked extremely well, better than most WiFi have had to pay for on other airlines.
My only problem was on the last flight, I’d got so used to it working I’d forgot it wasn’t on every aircraft and planned to use it.
This is a very positive move for MH.
