There’s no doubt that teachers are underappreciated — especially in the midst of a pandemic — but Qatar Airways is trying to show its gratitude. In honor of World Teacher’s Day on October 5, the airline launched a promotion giving away 21,000 round-trip tickets to teachers around the world.

The initiative began on October 5 and ends on October 8 at 9 PM EST. Winners will receive a round-trip economy-class ticket to any of Qatar Airways’ 90 destinations worldwide. They will also receive a voucher for 50 percent off one future round-trip ticket that they can use for themselves or a loved one, valid through September 30, 2021.

To enter, teachers must submit a form on the promotion website, which includes some basic information like their school name and teacher ID number. The promotion is only valid for individuals living in countries where Qatar Airways operates, and winners will be expected to pay the airport taxes. Tickets are also valid for two years with unlimited change dates.

Akbar Al Baker, Chief Executive for Qatar Airways, said in a press release, “We at Qatar Airways are incredibly grateful for the commitment and hard work of teaching professionals around the world who continue to educate our young people in these times of uncertainty. We know that it has not been an easy task, yet teachers have been incredibly resourceful, turning to online learning and other methods.”
