More than 1,000 people flown into the small Colorado resort town of Crested Butte for the filming of Anheuser-Busch's Bud Light advert had problems leaving the party.

The beer giant paid 500,000 dollars to paint several blocks of a central street blue and temporarily revamp the town into fictional Whatever, USA, for its Up for Whatever campaign.

The company said the travel delays stemmed from a large number of people trying to depart the Gunnison-Crested Butte Regional Airport after the two-day event. Some participants complained about the delay on social media.

A Bud Light spokesman said the company has a "process in place" to have all visitors return "safely and smoothly" to locations nationwide.
