Total net flight bookings to the U.S. between January 28 and February 4 are down 6.5 percent compared to the same period the year before, according to data from travel analysts ForwardKeys. Net bookings from the seven effected countries were down 80 percent.

ForwardKeys says their data suggests the travel ban is putting people off travelling to the U.S.

“The data forces a compelling conclusion that Donald Trump’s travel ban immediately caused a significant drop in bookings to the USA and an immediate impact on future travel,” said Olivier Jager, CEO of ForwardKeys, in a press release.

“As inbound travel is an export industry (it earns foreign currency), this is not good news for the U.S. economy. However, one must bear in mind that this is just an eight-day snapshot from when the ban was put in place and we will continue to monitor what happens as the political situation develops.”

Meanwhile, flight search demand from international origins fell 17 percent between Trump’s inauguration and the implementation of the executive order, according to Hopper, a big data company that analyzes airfares.

Hopper found that flight search demand had fallen in 94 out of 122 countries it analyzed, and international demand is down for all major U.S. destinations.

“We have seen little impact on pricing so far, but the airfare market typically takes weeks rather than days to react,” said Patrick Surry, chief data scientist at Hopper, in a research note.

“Last year, we saw only a 1.8 percent decline for the comparable time period which suggests the change is not a simple seasonal effect.”

Since the travel ban was implemented, demand has recovered slightly but is significantly below expected levels, according to Hopper.
