yes it is, read about what alpa used to be like

When Lorenzo started New York Air with non union pilots who were going to earn less than the going rate, ALPA launched a million dollar publicity campaign against them. Pilots even threatened to boycott Pepsi because a Pepsi bottler was on the board of Lorenzo’s main company, Texas International. I didn’t hear any sort of uproar like this with Jetblue or the impending Virgin America, instead ALPA insists that jumpseats should not be used for retaliation purposes.

what other industry do you see people giving free rides to work to the people undercutting them? This is one reason the airlines are in such a mess.
