Win a bet with your friends. Ask them to name Denver's busiest travel day of the year.
It's not around Thanksgiving, and not Christmas, either.
It's today: June 30. The airport set a record for busiest day ever.
An estimated 197,000 passengers were expected to pass through the airport Friday; that's larger than the population of Fort Collins.
The airport guesses 1.3 million will travel through DIA during extended holiday weekend - June 27-July 3 this year.
Be prepared if you're one of them; several days should top 195,000, according to the airport. Standard rules apply: get there at least two hours early for a domestic flight.
Heath Montgomery, DIA's spokesperson, said all TSA checkpoints have been operating smoothly.
Montgomery guesses there will be about 50 new "busiest days ever" by the end of August.
