United Airlines plans to restart several key Asia routes from July with services to Tokyo-Haneda, Hong Kong, Singapore and Seoul, South Korea.
It comes as both Hong Kong and Singapore started allowing the resumption of transit traffic this week.
United has indicated that it also wants to restart direct flights to mainland China.
United is also adding transatlantic services from Washington, D.C. and San Francisco to cities in Europe next month. It is also relaunching more services to Latin America and the Caribbean in July.
