First my motivation for booking through united.com is that I have $400 in travel vouchers and would like to get the united miles.

I can see the flights that I want on Copa.com for ORD-LIM, but the connection times are just under 90 minutes.

I can't get the United.com to show me flights with connection times under 90 minutes.

I've searched, but I don't think I'm searching with the right keywords.

Alternatively, if I paid the $25 phone fee, would United book such a flight that way?
