Using the T5 lounges would certainly be easier (I likely would go to the Galleries First Lounge rather than T5B), but given the length of the layover we’d both rather endure the hassle to spend time at the CX and QF lounges. Or maybe we’ll head into London for a late lunch (though it sure would be nice if HEX offered a same-day return discounted ticket like some cities — e.g., HKG, ATH — do).
