cancel flights for lack of crews
airlines dont cancel flight as they have a full year Flights program ,( when to fly, where to fly...)
hiring pilot is more expensive than keeping planes grounded, but it doesn't mean the aircraft are fully grounded waiting for his pilots, they just don't book more seats if the planes are full..
like in a restaurant, when the room is full, you wait outside or go eat somewhere else, they are not going to close the restaurant, because they need more chefs!
SO DON'T BELIEVE THERE IS A PILOT SHORTAGE AND PLANES CAN NOT FLY...IT IS A LIE!
the real shortage is for dentists where people wait 8-12 hours in line in the street to extract a bad tooth...if you want make a good living and make money, you know what to do!!!
