Onur give you 15kg hold luggage and 5kg hand luggage
Jet2.com have 22kg hold luggage and 10kg hand luggage
As Stoop says Onur change and cancel many flights, we have friends coming today, they booked Monday this week with Onur air to fly back to Doncaster on 4th May. They got a call Thursday to say the flight was cancelled and now have been offerd a flight 3 days earlier. I would reccomend Jet2.com out of the two mentioned
