We had to change flights in Reykjavik and the outgoing flight was send to gate D23, where there were NO SEATS in the lounge. And in general, there were not enough seats for transferring passengers in general. After the three hour flight from London and then expecting a 7 hour flight to Seattle, having to stand & mill around for over an hour was rather unpleasant. We had booked Business Class and were assigned seats in the bulkhead seats, row 1. This made a MOST unpleasant 7 hour flight from Reykjavik to Seattle. The flight attendants had stored some of their carry-ons in the overhead bin just above us so it left us little room to place our carry-ons that was convenient. The seats in Business Class are too deep for shorter people and without ANY form of leg rest/support, we struggled to be comfortable for the entire flight.
