The chief executives ofDelta Air Lines,United AirlinesandSouthwest Airlineswill meet with President Donald Trump tomorrow, joining a group of airline chiefs due to meet with the new president.

“Doug shares President Trump’s commitment to modernising our nation’s infrastructure and looks forward to working with his administration to ensure all Americans have access to safe and efficient air travel,” he says, adding that Parker has informed the White House of the conflict.

The Air Line Pilots Association (ALPA) heads for bothDeltaandUnitedconfirm today that the airlines' respective chief executives Ed Bastian and Oscar Munoz will attend the meeting. However, neither carrier has confirmed the attendance of their respective executives.

A Southwest spokesperson confirms that its chief executive Gary Kelly will attend the meeting.

White House press secretary Sean Spicer confirmed the meeting between Trump and airline chief executives on 9 February during a media briefing yesterday. He did not comment on who will attend.

Topics of discussion at the meeting are likely to include the president’s proposed USD 1 trillion infrastructure plans, which could include upgrading the US air traffic control system, as well as the on-going dispute between American,DeltaandUnitedand the big Gulf carriers over open skies and the expansion ofNorwegianto the USA.

"Obviously, the president's going to want to talk about economic growth and job creation, how he's enacting orders to make sure the country's safe,” said Spicer on 7 February.

The press secretary tacitly affirmed the administration’s support for Norwegian’s expansion, saying the move is of “huge economic interest” to the country. He cited the carrier’s plans to hire US crews and buy US-built aircraft.

US labour unions have been outspoken against the granting of a foreign air carrier permit toNorwegian's Irish subsidiaryNorwegian Air International.

In 2014, American,DeltaandUnitedfiled an objection toNorwegian's application for a foreign air carrier permit for its Irish-subsidiaryNorwegian Air International(NAI) citing a need to maintain labour and social standards. Despite this, the Obama administration granted the permit in December 2016.
