The biggest problem I see is that you are coming in on a charter carrier, which means they may not through check your baggage. If that is the case, you would have to recheck in SEA
(you always have to reclaim it for customs, but if it is already tagged, you can just put it on the transfer belt and it is gone). Getting through customs & immigration and then getting your luggage from the South Satellite all the way to the north end of the terminal to check in takes a while. It would be very difficult to do that and get your bags in before the minimum bag check cutoff time. UA
has no transfer desk that I know of in the South Satellite.
If you have no baggage, or your charter carrier can through check it, make sure to check in online for your UA
flight and print out your boarding passes. SEA
has no transfer desks for international arriving passengers. It can be quite a trek to get to the UA
check in counters, and if there are lines, you may miss minimum check in time.
is always among the best for on time performance. I wouldn’t worry about that. I would only worry about checking in and transferring because it is a relatively long transfer from international to Domestic UA
I wouldn’t worry too much about SFO
. Mainline to Mainline should all be in terminal 3. Also, flow control and delays are common in the morning, but by lunchtime, usually any delays have cleared up and the afternoon tends to run relatively smoothly. Also, check to see if UA
has a flight leaving later from SFO
. There may be a 4pm departure from SFO
, so if you miss your flight, you can be reaccomodated.
If you have never designed an airplane part before, let the real designers do the work!
