The United Kingdom and the US have agreed on an "open sky" agreement for flights after the end of a Brexita air service, said Transport Minister Chris Grayling.
The agreement means airlines will continue to fly from Great Britain to the USA after Brexit told the Department of Transportation (DfT).
Flights between countries operate on the basis of a US-EU agreement on open skies.
The Treaty with the United States is one of the nine bilateral air services agreements that the United Kingdom has replaced.
The others are with Albania, Georgia, Iceland, Israel, Kosovo, Montenegro, Morocco and Switzerland.
Discussions with Canada are "advanced" according to DfT.

Mr Grayling said that transatlantic flights helped bring the United Kingdom and the United States "even closer, strengthen our ties and support our economies."
Brexit's representative said: "This new arrangement and dealings with eight other countries around the world are proof that the UK will continue to be a major player on the world stage after we leave the EU."
Under the agreement, the EU's major air carriers currently operating between the United Kingdom and the United States will be able to continue their flight over existing routes if they continue to be owned and controlled by EU / EEA nationals or by UK nationals.
But any airline wishing to create a route between the United Kingdom and the US in the future that is not owned and controlled by UK nationals will have to ask the US government for a waiver.
The parent company, British Airways IAG, is registered in Spain and has shareholders from all over the world.
Chief Executive Officer of IAG to IAG, described the aviation agreement with the United States as "a significant positive development that we welcome."
He said he "facilitates strong competition and is obviously for the consumer".
Aviation consultant John Strickland said: "It is a positive message for British airlines operating in the US market that this agreement has been reached.
"It seems that sufficient flexibility has been agreed to allow different scenarios of either majority ownership in the UK or the EU, which is an important point for IAG, and Virgin, which is in the process of stacking."
Sir Richard Branson is 20% in the process of reducing his stake in Virgin Atlantic by selling 31% of Air France-KLM.
Theresa May, the Brexit agreement with Brussels, states that the UK and the EU have agreed to negotiate a "comprehensive air transport agreement" for UK-EU flights during the planned transition period, but the UK does not apply to the EU without agreement.
In September, the government warned that no deal could breach Brexit's air traffic disruption between the United Kingdom and the countries of the European Union.
