Dont even try to book a ticket with STG TOURS & TRAVELS, 55-C First floor, 1st Main Road,Anna Nagar East (Near Chintamani) Chennai-600102. I booked 5 tickets with them last year (MAA to IAH with emirates) for around 80,000. this year i asked them to book a ticket for aug 15. he said it will come around 1,20,000. he said he will give me a ticket with emirates for 82,000 on aug 23. he asked the passenger to come to chennai saying that he can confirm the ticket on aug 23 only. but he is asking more than 1,00,000 with multiple airlines from delhi. who will pay upto delhi?, i dont want to travel with multiple airlines. they will ask for these things at the last movement. but they will speak very very nicely until you get your ticket. you will trust them like that (i did the same for the last 2 years), hell such a worst experience. then i booked a ticket with yatra.com for 90,000 on the same day.
they will not pick up your call on the last day, their office staff will say they went to airlines office to get the ticket for you, other staff will ask you to go to airport, where he will come with the ticket.
finally they will not attend the phone. WORLDS WORST TRAVEL AGENCY.
