Daily rewards if we enter each day to World of Airports.
That only works if you have other revenue streams from ads etc to supplement the ability to give that away, devs only source of revenue is from golden plane purchases, which means if you want free ones you have to work for them by playing the game
The devs have strategically set up the game to earn gold planes in various ways ( achievements, flying etc), if you can buy then you do that quicker and the devs earn money to invest in the game. No revenue , no game.
This is one of very few free games I know of without ads. Yes they could incorporate them and then give gold planes away, but I for one hate ads and it’s one of the reasons I love playing it.
So no, can’t support this, sorry
