Does anyone know what is ticket booking algorithm followed for AC double decker trains for Bangalore to Chennai. (train no 22626)
My elderly parents would be travelling and I want them to get either middle deck or upper deck. Currently I booked 2 months in advance right in morning
thinking I would get middle deck but sadly I got lower deck. Right know 998 availability is there and I am thinking to rebook and try my luck again. Is there any sequence followed while allocating seats like lowed deck...
more... first, middle deck next and then upper deck for 1 coach and then go on to next coach.
Is there any specific availability point where if I book I am likely to get middle or upper deck ?
