Reply #5: Uh..guys? It's why they're called 'scheduled airlines'.

[trof]

By law, airlines can't cancel a flight because they didn't sell enough seats. Or because few people show up for the flight.

And they had to get the aircraft to Heathrow for the passengers on the return flight.

Now you can just ferry an airplane to do this. Usually with just cockpit crew, but sometimes with cabin crew also.

Hell, at least they had 5 paying passengers to help with the gas.
