short-haul fares like this move fast in both directions — booking one to three weeks ahead is the usual sweet spot, and same-day walk-up fares are the worst case.

The cheapest month depends on the demand calendar at Hong Kong — school holidays, the Christmas–New Year peak and major local events price highest, and shoulder-season months between them price lowest. Rather than trusting a generic answer, open the fare calendar on the search above: it shows real prices for every date this month and next, so the cheap windows are visible immediately.

It depends on your nationality, not on the route — two travellers on the same Hanoi (Soc Son) → Hong Kong flight can face completely different entry rules. Check the destination country’s official immigration site or your foreign-ministry travel advice for your passport, and do it before booking: some destinations require a visa obtained in advance, others issue visas or waivers on arrival.

Whatever the fare you buy includes — baggage is set by the carrier and fare class, not the route, and the carriers on this pair (Cathay Pacific, Hong Kong Airlines, Vietnam Airlines) price bags very differently. Low-cost fares usually include cabin bags only and charge per checked bag; full-service fares typically include at least one. Compare totals with your bags added, because a dearer fare with bags included is often cheaper overall.
