We pay enough for the app right? How about making all planes free.

They would go bankrupt if they made all the planes free, therefore, no more Inifinte Flight. The devs also live off of the money that they make from this app, they have to make it financially sustainable, so they can bring us awesome new updates. We also have lots of other free planes, the A321, A380, 737-700 etc. People have asked this questions tons of times, on their Facebook, the forum, Instagram, and the answer you will get is always no.
But after a while the money the devs have will be finished, so they need more people to buy.
