Panic - on the M40 in heavy traffic for 8pm flight - need to go to T2, then to T5
Long story, but my wife is taking family friend, 17yo, in a dash to LHR after she had lost her passport and therefore missed her normal transportation from Oxford. She needs to go to T2 to collect the 17yo's luggage, which is with friends there, and then get to t5 for bag drop.
What is quickest way from T2 to T5? Tube or back into the car and drive around to T5? Thanks for any advice.
She has checked in on the BA app and the flight is on time, 8.05pm
