Not concerned about the flights. More concerned that carriers can't sell seats for £30 in July and expand and be profitable.
Call me old fashioned, but when ZB was smaller and offered a better product (scoff, drinks etc.) it was on to a good thing. Now, the goal of piling ever higher and selling ever cheaper might be coming to the end of the line. The LCC model will be around for the long run but the days of boundless LCC expansion and cut throat competition might just be running out of steam.
I'd be happy to be wrong, I like being able to buy seats for the price of a curry.
