“To give customers more choice when it comes to booking or rebooking their Summer 20 vacation, today we are announcing thousands of new flights, representing nearly 100,000 additional seats, to destinations in Greece, Turkey and Portugal.
“The demand for vacations to these destinations tells us that summer 20 is alive and well in the minds of our customers, and our decision to increase capacity is a direct response to that demand.
“We can assure independent travel agents, clients and our partners in the Balearic Islands that we remain fully committed to these fantastic destinations.
“Bookings for next summer look good and we look forward to doing what we do best: working with hoteliers and our partners in Ibiza, Mallorca and Menorca to ensure guests enjoy their well-deserved vacation. “
