DENVER (AP) - Passengers are upset after a Lufthansa flight leaving Denver for Frankfurt held passengers on board for three hours without air conditioning.
Airport spokeswoman Laura Coale says paramedics were called about 90 minutes into the delay Sunday while the plane remained at the gate. No one suffered serious medical problems.
Lufthansa did not return a phone call seeking comment.
