Flylolo sounds like a nonsense airline. There is no information in the booking engine showing operating airline or aircraft type. Their mantra is to offer cheaper flights in the peak, which sounds also nonsense, airlines have excess demand in the peak summer therefore don't need to discount.
I'm falling to see how this strategy stacks up. Charter/ACMI operators (Sounds like Jota territory to me) can charge a pretty penny especially in peak summer when airlines are in dire need of aircraft last minute, and now with 737Max problems, there is no way they'll secure aircraft in the peak at sustainable rates. Equally, what happens when the revenues they generate fall short of the aircraft hire costs???
