OP. It has been reported that I is Flex but the best way to know is if you have a booking code as you can tell from that. 4th letter from the right. F = Flex Plus / S = Flex / P = Saver / R = Special
the way to know the booking class is look at the reservation on the airline(or travel agency eg Amadeus) screen At ticket office/transfer desk EK (or other airline) will if they're in a good mood print out the short version of the reservation. The letter after the flight no.denotes the booking class e.g.EK 123S.
