Take a look at the FAQ pages of cleartrip.com and Yatra.com, especially Question No. 2 under Troubleshooting. Someone should be fired for such blatant plagiarism. And for this reason I think that, that someone is at yatra.com.
UPDATE: Yatra is the guilty one. In their FAQ Question No. 5 under Registration states that to change your account information you need to
Sign in to your Yatra Account. Thereafter go through each tab and update the necessary account information. Click on the save button. Your account information will be updated.This is simply false. After signing in to yatra there is no way to change account info and I can see no tabs !!. Yatra, when you copy atleast delete the parts which doesn't apply to your site !! (Cleartrip.com account details can be edited just the way it has been described in the FAQ).
