Have used Onur lots of times and have only had slight time changes that did not matter to us. As far as value for money you cannot beat them we managed to take 4 of us for the last 4 years for cheaper than it cost or 2 people with any of their competitors. Lets just say you get what you pay for and I am happy with that, plus leg room is much better than Thomas Cook sardine cans but each to their own you pays your money and you takes your chance. By the way have never flown with Jet2 so cannot comment on their level of service.
