Every airline has it USP's, certainly Ryanair has many and easyJet does too. A passenger can have an awful experience on any airline even a well established legacy carrier who has all the trimmings. Ironically, the two compete less and less and are after different markets, and someone mentioned earlier that they only go easyJet if they have to, or if there is no other choice, well as far as Ryanair or easyJet are concerned there are so so many markets where there is in fact no choice love or hate them but you must use them to go on certain routes. Dublin is a case in point many of the busy routes like LPL, LTN, STN, EMA, LBA, NCL, you only have Ryanair. The same is true of many markets easyJet serve.
They have their distinct USP's
Ryanair has to be punctuality and price, a young fleet of Boeing Aircraft and a huge network of routes.
Easyjet has to be convenient airports, the staff (I feel that as they are often local to the base, as is the case here in Belfast, the staff know a lot of the customers), frequency of flights between key business centres.
Both are profitable giving shareholder return and creating employment.
So lets agree that they are not perfect and recognise what they are strong at respectively.
