Connections, delays and PHL...

I plan too much. I read too many reviews. I check vaction flight performance daily. Sad, I know. We are going to Cancun again in July. Our flight from Dayton to Philly has an on time rating of 78%. (That fact that I know that is nerdy I know.) Looking at the length ofthe delays I realized we have a 1 in 10 chance of not making the Cancun connection. It is a one hour layover and we have to take a bus across the airport. My travel agent is much more positive. "Well, that means you have a 90% chance of making it."
