After 18 years flying as an airline for the price conscious, Allegiant Travel Co. wants to add real estate development to its list of corporate activities. The company is embarking on an audacious plan to build a 22-acre resort compound with a hotel, condominiums, bars and restaurants in Port Charlotte.

The real estate offshoot, called Sunseeker Resorts, will have a 75-room hotel, along with about 720 condo units, ranging from $650,000 to $1.1 million based on size. The property, when finished in late 2019 or 2020, will also include North America’s largest private-resort swimming pool.
