Slightly OT as it is BMI - but travelling BD Domestic you can serve up a double whammy if you are boarding from one of the gates (8a,b etc I think?) that are right by the 'back door' to the lounge. Time it just right and you can flounce directly from the lounge to an empty Business/*s-*g line much to the annoyance of a queue of Y pax who have been milling/queueing there for 10/15 minutes since the screens told them to go to the gate. Some of them even seem to stare at the lounge door to catch you swigging the last of your G&T prior to opening the door...
