Hi all! A bit of a last minute question. Wife will be traveling on my reward miles (Economy, I am 1K) and will have to spend ~5 hours waiting for people in her group to arrive at Heathrow. I see that there is only one Star Alliance Lounge on arrival side and it's only for Business/First. Any change for an exhausted Economy to sneak in (she'll look the part for being exhausted, that's for sure!)? Or other alternatives for comfortable waiting? Thanks!
