High Maintenance Cost, Replacing Aircraft

[pf94]

HI,

Airline: Airline Mogul - See my airline

As I said in the title, I have 18 Lockheed aircraft that are around 12 years old, which is the reason why my maintenance costs are pretty high. I will replace them with brand new A310.
My question about that is, if it is better to close all these routes and replace them when I have the money to buy all the A310's or is it better to replace every day one lookheed with an A310? Because that's the amount of A310's I can afford every day.

Thanks,
Paul

I'd replace one daily, but with the amount of money you earn, I don't think it will make a huge difference closing all the Lockheed-routes at once. Maybe it is even better.

But the difference would be minimal, so you decide

Okay thanks. I think I replace them one by one.
