It's a 7 hour flight.
Take some quality sandwiches/delicatessen stuff and some fruit, walnuts and cheese, eat the un-tomatoey bits of what's offered and enjoy the rest to the envy of the neighbouring passengers.
Also if anyone has been on this flight recently, could you also tell me what the loads were like.
Do you want to know what the loads were like out of a purely historical interest or do want to know the likely loads on the date of travel. If the later, DoW might be helpful.
