To celebrate its new service between MidAmerica St. Louis Airport and Orlando, Fla., Allegiant Air is inviting people to register for a chance to win one of three free trips on its inaugural flight between the two cities on Wednesday.

The prizes include a vacation package for four which will be given away Saturday, and two separate "Pack Your Bags" vacation packages for two that will be given away to adventurous travelers at MidAmerica Airport the day of the inaugural flight.

To enter for a chance to win the family vacation package for four, local residents need to visit Eckert's Farm in Belleville between 11 a.m. and 2:45 p.m. on Saturday, and stop by the sign-up table at the main entrance to guess the weight of the pumpkin on display. Those registering their guess between 1-3 p.m. will instantly receive a free five-pound bag of golden delicious apples, courtesy of Eckert's, while supplies last.

The entrant with the closest guess will be announced at approximately 3 p.m. Saturday. The winner will receive round-trip flights for four on Allegiant's inaugural flight departing MidAmerica Airport at 3:50 p.m. on Wednesday and returning at 5:35 p.m. Sunday, Nov. 11. Accommodations are courtesy of Sheraton Vistana Resort Villas Lake Buena Vista and include four free tickets to Legoland Florida.

Spontaneous travelers interested in trying their luck to win one of the two packages to be given away as part of the festivities celebrating the inaugural flight will need to show up at MidAmerica Airport with their bags packed between 11:30 a.m. and 1:30 p.m. on Wednesday to register for their chance to win.

The two winners will be drawn at 1:30 p.m. Each will receive round trip flights for two on Allegiant's inaugural flight. Accommodations will again be courtesy of Sheraton Vistana Resort Villas, Lake Buena Vista, Fla.

Following the prize drawing, representatives from Allegiant, MidAmerica Airport and St. Clair County will participate in an official ribbon cutting to mark the start of the new passenger service to Orlando.

Allegiant Air is returning passenger service to MidAmerica St. Louis Airport more than three years after it became the fourth airline to abandon the Mascoutah airport.

The Las Vegas-based discount airline will offer two non-stop round-trip flights a week between MidAmerica and Orlando Sanford International Airport. Sanford is the smaller of Orlando's two main airports and is about halfway between Walt Disney World and Daytona Beach, Fla.
