6:50am flight, leave hotel at 5:15am, is this enough time?

Been awhile since I've been to SIN, but if I recall, taxi to airport takes 20-25 mintues at that time in the AM which would leave 1hr 15min to check in (I have status on UA so checkin should not be long) and SIN customs are a breeze.

Did I figure correctly?

Absolutely no problem.

You will still have an hour to kill before boarding.

Cheers

thanks.

There may be a line at the gate. Allow enough time for rigorous security, but it seems pretty unpredicatable.
