I am traveling to Vegas the second week of October. I am spending a day there and then traveling to see a few parks. In February I saw in 3 days Red Rock, Valley of Fire, Hoover Dam and took a one hour flight to Grand Canyon National Park for a few hours there so this time I am going to see Bryce and Zion. I know people suggest spending days at each park but that isn't an option. My question relates to flight times so that I can maximize my time at the parks but not miss my flight back to Miami. Vegas has a nonstop 11pm flight to Miami and Cedar City Utah has a 6pm flight that makes two stops. Which flight do people believe I should take in order to spend as much time as possible at Bryce? I was told it takes 5 hours to get to Vegas from Bryce and I should allow 90 minutes from the moment I drop the car off until I board the plane. The 90 minutes sounds right based on my prior trips to Vegas. Based on those times, I think I would need to leave Bryce at 3:30 since there is a one hour time difference. I have never flown out of Cedar City Utah. To the people who have flown from that airport, how long do you believe it takes to get from Bryce to the airport and to then drop off the car? Some places have simple car drop off procedures but others require more time and shuttles from the car rental place to the airport's terminal are not frequent. In your experience, is traffic bad to this airport? Are security lines long for early evening flights?
