Yes, a bit irritating on the operating hours. Depending on the site you visit, opening time can be 7:00, 7:30 or 9:00. Oh, and it could vary by day of week. Have a mid-am flight out of T6 Monday and while I don't mind the walk over to TBIT, it would be a significant waste of time to walk over there only to find the lounge to be closed.
So... does anyone have any recent intel? Much appreciated.
