Hi! I'm a UA 1P, I'll be flying in from LHR (in C) connecting domestically with a long layover, does anyone know if
a) I'm entitled to use the UA Clubs? (CO says departing intl. only, but I've accessed SFO lounge arriving on LH F)
b) If it's possible to move between terminals to use to the Air New Zealand or the Air Canada lounge? (both also look much more appealing than the UA Club).
