Cheap Flights from Dublin to Hanoi

Give the search a few months of runway, because long-haul fares with a connection seldom drop close to departure, and midweek departures tend to price below weekend ones. The fare calendar here runs from September to July, and February is the low point of the year for tickets, falling in the cooler stretch of Hanoi's year before the hot months arrive. Plan around the holidays at both ends: Christmas and New Year lift demand out of Ireland, while Tet, the Vietnamese Lunar New Year, shifts with the lunar calendar and makes travel around it busy on the Hanoi side.

The mix is almost entirely full-service: Aer Lingus, British Airways, BA CityFlyer, Air France, Turkish Airlines, Qatar Airways, Etihad Airways, China Eastern Airlines, Thai Airways International and Malaysia Airlines all appear here, and none of them is a low-cost operator. What separates them is where you change planes — the Gulf carriers via their home hubs, the European and Asian lines via other cities — and what the fare includes. A checked bag and meals are usually part of a full-service fare, but fare families vary, so read the inclusions before you pay. BA CityFlyer also sits next to mainline British Airways in the list, so see which one operates your first leg.

Arrange your entry papers before you fly: check Vietnam's visa and e-visa rules for Irish passport holders and have the documents ready for immigration at Noi Bai. The airport sits a fair distance from central Hanoi, so plan the way into town ahead of time — an airport bus, a licensed taxi or a ride-hailing car are the usual choices. Traffic can slow the last stretch at peak hours, and in a taxi without a meter it is worth agreeing the price before setting off. Keep some local payment with you for the ride, as not every driver takes cards.

Country facts: Wikidata

• Check whether the connection is on one ticket or two, since a separate-ticket itinerary leaves you to rebook if the first leg is delayed.
• Check the connection margin at the stopover and keep it comfortable, as a missed onward flight to Noi Bai is hard to recover.
• Check the baggage allowance on every leg, because a low-looking fare may leave the checked bag out.
• Check the passport validity and the visa or e-visa rules Vietnam applies to Irish citizens before you pay.
• Check the fare calendar from September to July if your dates are flexible, with February the low point.
• Check the total journey time per option, as the airlines here connect through different hubs.
