UA statement on the web site:
New TSA security measures
The Transportation Security Administration (TSA) has issued new security measures for all flights departing from any foreign location and traveling to the United States. This is in addition to the normal screening that all customers go through to enter secured areas. All customers should allow extra time for check-in and the boarding process and, as always, should check their flight status before departure.
Nothing about IFE, or domestic flights.
