Increased Airport Security Screening from any non-U.S. location TO the United States:
For all flights departing from any non-U.S. location TO the United States, the Transportation Security Administration (TSA) has issued new security screening measures. This measure is in addition to the normal screening that all passengers must complete to enter secured areas. All passengers should plan to arrive at the airport at least three (3) hours in advance of their flight departure to allow extra time for check-in and the boarding process. Recommended airport check-in time for Delhi, India is currently 3 1/2 hours.
As always, be sure to check your flight status information before you head to the airport.
