i flew back via delhi where i have to wait for 10 hrs transit. The only scary thing is this airlines staffs man. they took my green card n paspport including some other old couples for at least 3-4 hrs. we were so worried n didnt know where to go. those folks were like wt we should now? but at last the guy showed up with our documents n boarding pass. by the way i got my ticket frm travel agency.
