Remarks: Getting to the parking with more than 3 hours delay and also an aircraft change. Initialy we were on board a B757 G-BPEI but after we were all on board the hold door didn't close. The capt decided to make an aircraft change to a B767 G-BZHA. This took for almost 2 hours. After all everything went right despite that I lost my second connection. BA staff like allways fantastic.
