Thank you all for your advice. As madhesi has stated - I am really deseperate to have some one as companion as time is approaching faster. While ideas provided are very useful and will be the one to follow, some time flight of gulf are delayed at london and hard to get boarding pass unless one can talk/argument. Hopefully such things will not happen to my parents. I am going to DC airport to leave and to get boarding pass for my parents and hopefully I will meet someone there. I am still looking for some companion. Thanks for your valuable suggestions.
