I just lately flew Icelandair from Seattle to LHR. The 1st flight was a Boeing 757-200. I’m 6’four and booked an extra leg space seat. Not only was I cramped with my knees almost hitting the seat before me, even so the seat alone was not extremely vast and not relaxed. My 2nd leg from Reykjavik to London was on the 767-200 and wasn’t much bet
