I was at T3 for a BA flight to BUD last week.
Key notes:
- After 11am CX lounge empties for 2+ hours (no flights).
- AA lounges close 4pm
- QF only upstairs open until mid afternoon.
- BA has a QR code ordering system - didn't try the menu.
I suggest hit CX early, then AA, wander through QF on the way to BA and then whatever.
QF downstairs is open in the morning too before the PER flight, closes at about midday.
