12163 can be speeded up a little bit and slot can be changed...such that
12163 departure from LTT: 12:30 PM
12163 arrival at MAS: 08:40 AM
12164 departure from MAS: 12:30 PM
12164...
more... arrival at LTT: 08:40 AM
and some RSA has to be there... Just my opinion
even now in the present slot.. it has TAT of more than 24 hours at LTT.
