You can have all the cheap aircraft you want but you still have to fuel and maintain them. Staff, navigation and ground expenses are still there as are a degree of overhead. Even more fundamentally, most of the (I assume) profitable routes have already been backfilled by competitors. Throw in continued Covid-related tomfoolery and you have a recipe for unmitigated disaster. This outfit has not got a cat in hells chance of making it in my opinion.
