I am travelling IAD-BEY in about a week- IAD-LHR-BEY. Business class... my flight from IAD there is no big weight restriction on luggage, its standard; two 70 pound? or kilo suitcases. BUT, on the second leg of the flight, I can only bring ONE 50 pound / kilo suitcase. Mind you, my trip is for 3 weeks, and I am not a master of packing light. Last year, I flew the same trip, except the LHR-BEY was with an A321. Now its going to be an A320. Are these restrictions because of MTOW issues??...because the A321 had no problems. I like both the A320 and A321 (I do feel better flying to BEY on a 321 because its bigger...it feels more appropriate)... but this is going to be a pain in my bum!
