Major airline faces backlash after using ‘ghost flights’ to exploit a legal loophole: ‘They weren’t even selling tickets’

The airlines always complain about the cost of fuel, I'm surprised they can tolerate this. 18,000 ghost flights for Lufthansa? Just last month I sat in a 100 degree cabin for about 45 minutes before take- off because the APU needed to be turned on by a ground unit. The pilot said he called for the truck. It never came. Later I asked a pilot friend of mine and he said they can power that unit themselves but it uses fuel and the airline probably has a policy against it. Screw you Virgin Atlantic!
