We do not publish a number for this, because we cannot measure it yet. Answering it honestly means watching the same departure date on this route over many weeks as it approaches, and that archive is still filling up — so any "book N days ahead" figure here would be borrowed from somewhere else rather than measured. What we can measure is which month is cheap: across 9 months of cached fares, Nov comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.

The current cheapest fares involve a connection, ticketed under Biman Bangladesh Airlines. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.

No — these are cached fares found on real searches (this one on 17 October). Airlines reprice constantly, so the booking search re-checks the live price before you pay. Fresher finds are far more likely to still be available.
