Eh, Finy, the two-letter IATA code for Malayasian Airlines is MH.
MA stands for Malev, the Hungarian Airline!
To the question now: as having flown all my life, NO, it would not affect my flying life.
As for flying with MH, they USED to be a very good airline, but like so many others', cost cutting over the years' has brought them to a very sad state.
Have always, & always will, fly QANTAS as much as possible, on my itinerary.
QANTAS has provided me, over many years', very happy memories' & some exceptional flights!
May the 'Flying 'Roo' look forward to its' 100th Birthday, in a few years'!
