Nada - but it would be nice if CO set aside the IAH E Club upstairs as a BF International Lounge with a Delta-ish dinner/salad/dessert buffet, better quality drinks, etc. It's something they could put up and take down each day without needing to build-out a new club. The front desk could hand out passes to eligible visitors (BF boarding passes only) which would be shown to an agent after getting off the elevator.

They would need to open for HNL/NRT, then close, then re-open for Europe/South America. The upstairs area could revert to normal PC amenities and access outside those periods.

Significant value-add for minimal cost.
