On the face of it, good news, although I'm curious about what the end to end time from T5 to plane will be compared with T1. For example, I can arrive at T1 around 5.40-5.45 for my regular 6.35am to BHD and still get enough time in the lounge for a quick bowl of porridge and a coffee.
I'm guessing that more time will be needed at T5 to make that feasible? At that time of the morning, every extra minute in bed counts!
