Qatar Airways is continuing to operate four times a day to Heathrow but the frequency will drop to twice a day from April 1.
In a statement today, the Doha-based carrier said: “We appreciate this is a difficult time and that many people around the world are trying to find a way to get home.
“At Qatar Airways we continue to operate more than 150 flights per day so that as many people as possible can get home safely to their loved ones.
“As at 24 March, we are operating services to over 70 cities worldwide.
“We are constantly reviewing our operations to see where there is more demand and requests, and wherever possible we will add more flights or bigger aircraft.
“This is a challenging time for the aviation industry and we are thankful to airports and authorities and their staff around the world for their incredible efforts to help us get passengers home.”
