The main effects I can see are:
- Less business and tourist travel to the US.
As almost all journeys are return journeys, there will be a large impact on travel both ways. The impact could be sufficient to concern the yield managers. The ban appears to apply to almost everything from phablets upward that most pax carry. The regular traveler to the same place may be able to have bare bones or loaner devices at each end of the journey. Other travelers will abandon the travel.
As msbbarratt points out there are plenty of home grown and imported malcontents living in the USA, there are even more in Europe. Therefore, it makes no sense for this to be just an ban on international travel with electronics. Logically, if there is such a threat, then domestic flights should also have electronics banned.
The airlines should now make a more concerted attempt to alter the rather poorly thought out 'security' being imposed and start instead to move to the El Al pattern of real security checking the pax and identifying those who are a threat. A passenger who has several million miles on an airline flying similar flights several times a year to Europe or from New York to Seattle, is less likely to be a threat than a 25 year old making the 4th flight in a decade with the last flight a month previously to the Middle East.
Global Entry and other similar programs should be beefed up and offered as a security screening that will allow carriage of electronics. The current approach of just banning everything that _could_ be a threat is not workable in the long run - indeed it may just have hit its limiting level of acceptance.
