Passengers connecting from other airlines with carry-on baggage can only check-in at the gate. Gate check-in begins 1 hour prior to departure time.

Passengers with checked baggage connecting from a United flight who have checked their baggage through to their final destination may check-in at the gate. It is your responsibility to ensure that your baggage is checked through to your final location. If your baggage was only checked to PHX, you must retrieve your baggage from the baggage claim area and check-in at the DAC ticket counter.

Passengers with checked baggage who are not connecting from United or who have purchased separate tickets for their connecting flight must check-in at the ticket counter. You must retrieve your checked baggage from the baggage claim, then check-in at the Denver Air Connection ticket counter with your checked baggage.
