when i flew lhr-pen on 20th april this year.the 744 was near empty. on asking,cabin crew advised there are 386 seats on this plane and only 124 booked on......empty rows of 10 everywhere!!!...have a good trip!
Loads on MH7 can be thin at times - bear in mind there are 2 744s leaving often within an hour of each other for Kuala Lumpur in the evenings from London Heathrow... I do wish MAS would schedule MH7 to leave earlier at 6pm every night instead as its often pointless if there's room on MH1 if you're flying to KL since MH7 leaves earlier but lands later (at KL)!
