I work within the business aviation sector, and to be honest, I have no idea how these low cost airlines continue to survive after a year and a half of pandemic. There is no hoards of travelers and the scratch card and perfume sales can’t possibly be enough for maintenance, airport handling, parking and fuel prices, not to mention flight and ground crew salaries.
Regarding the baggage limitations, they are in place because of weight and balance restrictions of each aircraft. Cabin and hold space is limited.
These companies now employ all possible tricks to get paid additionally, or not to bleed money once flights are cancelled, even though it is very shameful towards the customers unable to get a response from the airline, especially since most people can not afford to loose the money they paid for economy tickets, let alone to pay for luxury travel.
I’m writing this just to offer a different perspective. Operating planes is severely expensive, did not really understand this before I started working in the industry.
