If you are travelling from ltt to bangalore and the waiting lists are high...then book till hosur as it falls under general waitlist so tickets get easily confirmed
now they moved the quota to Salem... So booking upto Hosur will not work now..
The Quota has been moved only for 11014, 11013 is still under General Quota for LTT HSRA and PQWL for LTT SBC.
it would be better to book till salem at least it will be cheaper than booking in CK & PT quota
