Sir Freddie Laker is back. The British entrepreneur who pioneered cheap trans-Atlantic flights before going bust in 1982 said he has received operating licenses for several routes for Laker Airways. The first passenger flight, from Manchester, England, to Orlando, Fla., will be March 28. Gatwick-Fort Lauderdale flights will begin in May, along with flights from Orlando to Gatwick and Scotland's Prestwick. Round-trip fares will start at $433. Sir Laker and Texas oilman Oscar S. Wyatt Jr. formed Laker Airways in September.
