Theoretically yes. But expect a surly look from the FAs (I'm speaking from experience). But to be honest, even the people at Etihad gave me a surly look when i took full advantage of the dine at any time.

One airline that does dine at any time very well is Lufthansa. Tell them you want your meal 3 hours before landing and will be prepared, heated and delicious, 3 hours on the dot. So German.


As a side note : Not all airlines offer express meal. EK does not offer express meal on their longest flights.
