I will be flying SQ2 from SIN to SFO this coming May and need to book a separate ticket on United to fly from SFO to SEA that night. I've been told by Singapore airlines they can connect my two seperate flights when I check in since they are both star alliance meaning I won't need to recheck in at SFO. May bag will be checked to Seattle. SQ2 is scheduled to arrive at SFO at 9:15 pm and the last United flight out is at ~10:35 pm. I am wondering if this is possible to make the connection? Anybody know if SQ2 arrives early on a regular basis? My wife and I both have trusted traveler/TSA precheck so we should be through passport control and security quickly and I feel like if all was on time we could most likely do it. Any information SQ2 status would be appreciated. Thanks!
