The GS Desk told me this would be "by the end of June".
"Dear Mr. LIH:
We just received word late yesterday that United is planning on opening an additional 30 United Clubs, 21 which should be opened by the end of June and the others by Labor Day. There are 3 additional in Chicago scheduled, 2 in Houston, one each in San Francisco and Washington Dulles, plus our clubs in Orlando, Fort Lauderdale and Las Vegas; these are scheduled for the end of June. We have not been provided the other line station locations yet. I hope this information helps and that you are able to enjoy the use of the clubs soon.
Thank you for being a member of Global Services."
Meanwhile agent in the B6 club this morning had no idea and was hoping maybe by the end of the year, but lack of security-cleared staff and the Chicago Transit Authority's service are major impediments to extending lounge hours or opening additional ORD lounges.
