Air travel is a privilege, not a right. If you can't afford a ticket, don't fucking buy it.
>they cannot make the following flight for other reasons?
Sure, but that's not skiplagging.
>Being on a megacorps side against consumers is strange behaviour.
I am siding with common decency. If you lie in the course of business just to save some pretty pennies, costing everyone else in the process, you are a scumbag and you deserve whatever comes your way.
If skiplagging becomes more common, airlines will ultimately raise prices for everyone to make up for the inefficiency and everyone loses. Screw that noise.
