Well im not so sure about Ryanair and Jet2, thing is Mr Ryanair and Mr Jet2 are actually quite good mates, i remember rumours flying when the two were seem having a business lunch a few months ago, rumours where wild that we were being bought out when it was juts a simple lunch
Everyone will have their own preference to airline, im sure easyjet will have many returning pax, personally i dont think they are a bad airline... apart from their customer service lol (sorry - bad 5 or 6 bad experiences with EZY now, would rather walk than fly with them now) but im sure ppl will say the same about jet2
Will be interesting to see how they both get on this summer at NCL as they do operate the same routes just about from NCL
Now if you look at LS in other places, they took on the mighty BA at MAN
Many destination BA served from MAN that LS then operated soon stopped
E.g. AMS, PSA, FCO to name but a few, oh thanks to BA for handing Jet2 the LGW on a plate! lol
