A controversy over whether Donald Trump gave classified information about the risk of IS using laptops against aircraft to Russia's foreign minister, Sergei Lavrov, last week, may also have had an impact on the debate, and helped airlines to avoid a wider ban for now.
They have good reason to worry about the possibility.
The transatlantic market is hugely important on both sides of the pond.
Around 31m people flew from Europe to America last year, reckons IATA, an airline industry group.
Business travellers, who rely on staying productive while in the air, would have been the most reluctant to fly laptop-free.
In any case, executives are often forbidden to put company computers in the hold for fear of theft or loss of sensitive information.
Business- and first-class seats account for only 13% of transatlantic passengers but provide half the revenue.
Following the ban in the Middle East, Emirates, a Dubai-based carrier, cut flights to America by a fifth (flyers were also put off by a strong dollar and worries about potential immigration difficulties).
If executives could not work on planes, it might cost the industries they work for around $655m in lost productivity, calculates IATA, based on an assumption that half of business-class passengers will lose five hours' working time per flight.
Research from Oxford Economics, a forecasting outfit, found that in Britain a 1% increase in business travel is associated with a ￡400m ($518m) boost to trade.
John Kelly, America's homeland-security secretary, had suggestions for business executives and families on how to cope with a laptop ban: read a book or magazine or, heaven forfend, talk to the kids.
Such tactics may not now be needed.
