Cathay investigates claim couple used crew rest area for sex

Cathay Pacific is investigating claims that an amorous couple in first class were allowed to use the crew rest area to join the 'mile-high club' on a flight from Toronto to Hong Kong.

The passenger, a doctor, has posted pictures of himself lying on the bunk - used by crew to rest between shifts on long flights - on a detailed blog about his 'amorous adventure' on the 15-hour flight on his way home from a Harvard University reunion.

It is unclear from the blog whether the rest area he claims to have been in was that for the cockpit crew or for the cabin crew, but his description indicates that the alleged incident took place in the pilots' bunks.

The unnamed passenger, an aircraft enthusiast who has posted a number of previous blogs describing his front-end flying experiences, says the romp on board the Boeing 777-300ER was made possible by an attendant he knew from previous flights. Three other passengers were in the first-class compartment.

The passenger wrote on his blog: 'On these long, long flights there isn't really anything to do after the meal service so my gf [girlfriend] and I were cuddling and watching movies.
