[QUOTE=ILS2;14530599]The most expensive has been 175 EUR for Y+ and 450 EUR for C.QUOTE]
I bought some VERY cheap economy restricted tickets for OSL-CPH-ORD/ORD-ARL-OSL in September, and decided to buy the OT even though they cost me 181 EUR (Y+) and 512 EUR (C). I do not know if the high price was due to the low ticketprice, or the fact that I bought OT early (in May).
