1. What should be the ratio of first class, business class and economy class between b737 and a320?
2. Can Tu-214 replace b737 and a320? (because the monthly rental fee is relatively low)
3. I have rented two Tu-214s. The lease is about to expire. Should I continue the lease?
4. I chose f70 for the initial aircraft, and the lease is about to expire. Should I continue the lease or are there other types of aircraft that can be replaced?
