I’m an ex employee worked with southall for one year, Best Advice is to avoid SouthallTravel.com working under different names as well with the tie up with skyscanner it will take you to(Traveltrolley, Cheaptickets, flysharp) under different names just to fool you,
If you have an urgent travel paying thru amex they will ask for copyies of credit card with a letter which is not safe at all,
Regards,
Saurav
