Just reserved flights on AA for our two daughters, ages 26 and 16, on a RT DFW to CDG in June. The return flight connects through LHR, from a BA flight that arrives LHR at 7:40, to an AA flight that departs LHR at 9:30. This will require a terminal change. Isn't this cutting it kind of close time-wise? Should I be concerned? On the other hand, since it is all on one PNR, if they miss the transatlantic flight, AA will need to put them on another one, right?
