How long does it take to go from Terminal 3 to the International Terminal ????? I'm arriving from Seattle on United at 09:37 and have to connect with Singapore Airlines to Singapore at 11:30 Do I have enough time ? Regards Mick Sheehan

Looks like you'll have to change terminals, from domestic to international. You'll be able to hoof it, but there's the airtrain that connects the terminals, which is quick and frequent. Security lines can be long, but move briskly. You should make it ok.

You will reach time. You can make it before 11.30am

You're going to be cutting it close, but you should be ok if you have TSA Pre Check.
