3 young Cubs fans and their families headed to Arizona for spring training

Three young Cubs fans received the trip of a lifetime at spring training in Arizona.

The fans are patients who are getting treatment at Advocate Children's Hospital. However, doctors cleared them for the trip. 

The three kids and their families took off Thursday morning from O'Hare for Mesa, Arizona, where they will visit the Chicago Cubs during spring training.

Gage Webber from Crown Point, Daniella Castro from Rolling Meadows, and Ga-el Alvarado Munoz from Des Plaines all face serious medical challenges, but for a weekend at least, the focus isn't about their health. It's about fun in the sun, with the boys in Cubby blue.

Two of the kids are cancer patients and one is a heart patient.

American Airlines is providing the all-expenses-paid trip.

The kids will be treated like VIPs, with inside access they cannot even imagine.

We also got word the kids and their families had dinner Thursday night in Mesa with a handful of players, including fan favorite Patrick Wisdom.
