Relative on UA2 (SIN-SFO) arrived today 12/26 at gate A1.

The switch to A1 from G, and problems with the A1 jet way delayed arrival around 30 minutes.

His connecting flight to Austin was at E10 and he arrived at E10 just as boarding started so it took him around 50-60 minutes to deplane, clear immigration, claim his bag, recheck his bag, clear security and get to E10.

He has GE/Precheck, was flying Polaris and did say that he was hoofing it after deplaning.
