Travel to the United States of America will now be a longer trip (much like its visa process). Due to the increasing tensions in Iran and Iraq, commercial airlines are rerouting their flights to the USA. The Directorate General of Civil Aviation of India, the country&rsquos aviation regulator, has advised all commercial carriers in the country to maintain vigilance and caution while traversing over Iran, Iraq and the Persian Gulf, according to news reports. Paying heed to the same, several airlines have decided to avoid the Iranian airspace and reroute their flights accordingly.
