Well, just few calculations:
If I start a contract in my Police Station, for 24h I can collect (6x Kiss Cafe, 6x Minimarket, 6x Outdoor Cinema, 6x Drive-In Theater, 6x Motel) without any bonuses 9,617 romantic paxs = 12 Condor flights daily.
Cupid's Arrow = 3 greenies = 516 more paxes
Together Forever = 4 greenies = doubles the pax output for 3h
To fly 300 Condor flights (half of required 600 flights for 3*) one needs to fly 33 flights daily for 9 days. It will require 24,750 pax daily.
You may calculate what amount of greenies it will require - 50+ daily. x26 Candy Hearts = 7,800 (even if all flights land with Lucky Ticket, 11,700 hearts total) - by far not enough to reach progress level 20.
