Now their website not being able to handle it is a separate issue... But other airlines manage it without any issues.
Allow me to explain. I am very familiar with fare basis and how that is linked to the booking class. But in my experience, if in a like for like POS and itinerary and any minimum stay is preserved and there is say a T class fare on Tuesday and I wish to change to say Wednesday I have never been told that T on Wednesday has multiple T's. In my experience with many other carriers, if T is there in the terms I have suggested one can be moved to that flight with applicable change fees. With LO they complicated it further. If you call them, someone verifies the availability for changes, but they have no idea of the price and then they transfer you to the "cashier", but you cannot contact the cashier first, who seemingly is the only crucial part of the process.
Lack I suspect you are more familiar with LO than I, nevertheless I think there is a very peculiar style of revenue management. In true FT style I have monitored flights I have been booked on to see for example Y and B only for sale and then suddenly U and T fares being opened in very close to departure. Flight goes out relatively empty. I have back office information to look at the actual loads and compare.
