Point Me to the Plane on a little known perk:
At certain airports, like London-Heathrow and Frankfurt, United has arrival lounges available (sometimes via a partner) and GlobalFirst/BusinessFirst passengers are entitled to access the lounge. However, at other airports, like Brussels, there are no arrival lounge facilities. In these instances, United will get you a room (or access to a gym) at a nearby hotel, so that you can freshen up. For example, in Brussels, United will provide a room at the Sheraton Brussels Airport Hotel.
You’ve got to be traveling on United internationally in First or Business to take advantage of this, but that’s such a great amenity. I imagine you’re going to have to do a bit of arguing with representatives to get this, so make sure you mention it when you’re checking into your flight.
