I see that this train has a combined AC 1 and AC 2 coach - HA1.
Looking at the layout of HA1, i see that it has 4+4+2 = 10 AC 1 seats. However, when I try to book from IRCTC for the first available day, it always shows availability as 0006 from LTT to CBE.
Are the remaining seats (4) not available from LTT and are available from some other station? Is it a quota? Please let me know.
