Last time I transited ORD it was via AA and I was doped up on cold meds so the Mrs. took charge. Now I am on AS award F on BA LIS-LHR-ORD-SEA. The last leg is of course via Alaska. Other than the joy of getting screened for every leg of the trip - how is checked baggage handled on Terminal 5 for BA to AS? Is there an agent to recheck baggage or do I get to cart it all to Terminal 2? I usually use my full allotment of baggage (3 x 70lbs.) but hauling it on a bus may not allow that.
