The mock wedding took place at Terminal E to celebrate the low-cost carrier's launch at D/FW. Nonstop twice-a-day service to Las Vegas and Fort Lauderdale begins on May 5.
"They bring a spirited sense of fun to the airport," said D/FW chief executive Jeff Fegan. "Low-cost carriers can grow and thrive at D/FW Airport."
Spirit announced that it will offer $9 fares on its routes for a limited time as part of the new service launch.
