Back to back: Excellent (use stairs upwards between gates 5 and 6, against flow); Transfer: Excellent if domestic, otherwise Reasonable; Landside: Reasonable
I tried and failed miserably to do this at BHD, I think most flights arrive and depart from Gate 4 which you can conveniently get from the Aspire lounge to. But I couldn't find any stairs, I think it was either gate 5 or 6 I couldn't find on the ground floor corridor (I saw gate 7) so traipsed out of arrivals and then back into departures. Is there meant to be a bypass security and duty free route or..?
