Anyone flying UPPER JFK to LHR on 15th March?

I'm taking the 11pm flight in Upper and have two friends on the same flight in Economy. I'd love to guest them both into the Clubhouse but rules dictate I can only do that with one of them. I'm wondering if anyone else is taking that route that night with a spare guest space they'd be happy to have used by someone? Failing that I'm going to have to try to be charming to whoever is on the desk

If it’s not too busy they have in the past sold entry on the day for approx £60.

The days of being charming to get entry have long gone.
