I will be booking two train tickets online for our travel from Lucknow to Jhansi on December 20th, 2013 overnight train and on 21st for Khajuraho, 22nd overnight for Varanasi, 25th for Allahabad, 26th for Lucknow and then from Lucknow we fly to Amritsar. How do I know what seats have been allocated to us. Will my husband and I get a seat/berth in the same compartment? I have a problem with my right knee and so is there any way we can get at least one lower berth. I am fine with walking but since my accident in April I have a problem bending my right knee and so if we both get upper berth it might be a problem. I am planning to book in AC 2A and AC 3A. The overnight journey I would have preferred AC 1A but don't see that class on the route we are travelling. Also what is the difference between the AC and sleeper. Is it advisable to travel on sleeper class if AC class is not available?
Any information will be greatly appreciated.
