Hi,

Need advise on transfer from International to Domestic flight. Will be flying in from SIN to IAH (Terminal E) on SQ F. Expected arrival time at IAH is 2:05pm.

In the midst of planning to purchase a separate ticket on UA for IAH-ORD. UA has the following flights out to ORD at 3:35pm, 4:54pm, 5:35pm and 7pm. Which one should I book to be safe so I won't miss the connecting flight? I'm gonna travel with 1 x hand carry with no checked in.

Where can I go collect my boarding pass for UA in this case?

Thanks in advance
