7 minute total flight - and was in something like a A320 or 737 IIRC.
The FA's served peanuts & sodas on the ground (dates & Arabic coffee in first class - yum), then came around and collect all the trash, and only after that do they take off.
The ground food service took far longer than the actual flight.
I have done the flight from Tahiti to Moorea a couple of times, which I think is about 17 miles on a pretty spooky old plane with chickens running around both airports.
