April is a special month for the Make-A-Wish Foundation -- and it's taking to the air to celebrate.

The nonprofit organization grants wishes to children, age 21/2 to 18, with life-threatening medical conditions.

It has launched a month-long campaign for air miles in honor of World Wish Day, the anniversary of the wish that inspired the foundation's creation on April 29, 1980.

Donated miles will benefit the foundation's chapters and never expire.

There are about 40 York County children waiting to be granted wishes, said Ann Waltman, York regional office manager.

The office processes about 50 to 55 a year, and the pending wishes are all in different stages and not because the office doesn't have resources -- although it could use more, she said.

"We're just very grateful (for donations)," she said.

Make-A-Wish Foundation of Greater Pennsylvania & Southern West Virginia, one of 62 chapters in the country, has fulfilled more than 13,500 wishes and is one of the most active in the country, the foundation says.

Three-fourths of wishes involve travel, and the chapter says it has more than 525 travel wishes and a need of 124 million air miles. The most popular wish is a trip to Walt Disney World.

Frequent fliers with air miles from Delta Air Lines, US Airways or United Airlines may donate to the cause. For more information or to donate miles, call the York regional office at (717) 757-9474 or visit www.wishgreaterpa.org.
