Is it correct that the smaller, the better when grinding GP, and the larger, like the A380, the better when grinding airport money?
A380, I would think I don’t own one so I’m not sure, is a best of both worlds, as when you get maintanence C you get 4 gp, and it being an x size, it makes about double what it usually does
If you want to make GP I would recommend the E190. Just 50k ₩ and gives 2GP after maintenance C. Saab 340 is also not bad, but it takes a little bit longer.
A380 gives ₩ on routes between mid and long range (less fuel on this routes). I wouldn’t use it to farm GP.
