People Express began another three-day sale.

The carrier, which said it took in more than 750,000 bookings during its half-price promotion in late September, announced that half-price fares will be available through Wednesday for all domestic flights between Oct. 9 and Nov. 19. The promotion was repeated because of high demand during the first sale, held Sept. 29 through Oct. 1, the airline said. The latest discounts apply to flights connecting with Britt Airways and Provincetown-Boston Airline, which People Express owns. They do not apply to flights from London or Brussels or to 14-day advance purchase prices.
