Checking in baggage during a stopover
Hello,
I'm flying in the summer MIA-JFK 28/08, JFK-LHR 28/08 (Arr 29/08), LHR-TLV 29/08. I'm intending to go home during my 10 hour layover at LHR. Throughout this whole trip originating in MIA I'm flying with 1 suitcase. Would it be possible to check in an additional suitcase when I return for the last leg of the connection LHR-TLV? I have the baggage allowance, just wondering whether BA systems would cause problems. If it makes a difference the first two flights are AA and last one is BA, all booked via ba.com on same reservation. I need answers from people with similar experiences cos if I have to leave the bag in London im screwed and the only other way to do it is schlep a case to MIA at the beggining of the summer which is not my idea of fun.
