Thanks anyway... maybe someone else has done this and will reply.
You know, that is a good question. I have orginated out of T2 on UA. I did visit the T1 United Club before hand ( used my T2 Boarding Pass ). I assume as long as you have a valid BP you should be alright. Just let them know that you are using the club if they question you.. ( however, this is only speculation on my part ) Let us know how it works out. Thanks and Safe Travels
