Da Nang International Airport (DAD)

Two terminals, joined by a walkway

The domestic terminal and the international terminal stand next to each other and are linked by a covered walkway, so a terminal change here is a walk rather than a shuttle ride, which is more than the busier airports at either end of the country can offer. The international building is the newer and brighter of the pair; the domestic one carries the heavier traffic and shows it at the morning and evening peaks.

Everything else about the airport is compact. Arrivals reach the kerb without a long march, the hall fills when several wide-bodies land together and empties again quickly, and the airside offering is modest — a handful of places to eat and paid lounges, but not much to occupy a long wait. It is a transit point rather than a destination in itself, and it rewards being treated as one.

Out of the airport: almost everyone is going elsewhere

Public transport from the terminals is thin — a single city bus route passes close by and stops short of being useful with luggage — so the realistic options are the metered taxi rank, a ride-hailing car, a hotel vehicle or a transfer booked in advance. Fares into town and out along the beach are low by most standards, and a prebooked car is the norm for the two long runs that a large share of arrivals make straight off the aircraft.

Those runs define the airport. South, the coastal road leads to Hoi An, whose lantern-lit old town is the reason many people fly here at all; north, the route crosses the mountain spur by tunnel or climbs over the Hai Van Pass to Hue, a drive worth doing in daylight. The railway that takes the same pass is one of the country's great journeys, but it leaves from the city station rather than the airport — train, bus and domestic flight each win a different leg.

Arrivals at a smaller border post

Da Nang is a full international checkpoint and the documents work as they do at the bigger gateways: an e-visa arranged online and printed, or a letter of pre-approval handed in at the counter when the plan is a visa on arrival. Who needs which is set out in Vietnam's entry rules, settled before you board rather than at the desk. The advantage of a small hall is that a single flight clears it quickly; the drawback is the same, because a cluster of charters landing together fills it.

The mid-country hub and the open-jaw trip

The airport's other job is domestic, and it is the natural hinge of a north-to-south itinerary: flights from both ends of the country meet here, which is what makes the middle of a trip flyable when the overland leg would cost a whole day. Planning around that — in at one end of the country, out at the other, with a flight into the centre — is the shape a two- or three-week Vietnam route usually settles into.

One caveat applies to arrivals from abroad that continue on a domestic flight: the connection is an entry, so the bags come off the belt and go back in after immigration and customs, even when both legs sit on one ticket.

The season that decides whether you fly at all

Central Vietnam has a pronounced wet season, and it is the one thing capable of undoing an itinerary built around this airport: heavy rain, flooding on the coastal roads and tropical storms off the sea can delay flights, close the road to the towns on either side and occasionally shut the airport altogether. Travelling in the central coast's storm season is perfectly feasible, but keep a spare day between the last flight out of here and an international departure elsewhere.

Practical: connectivity, cash and waiting well

Mobile data earns its keep here more than at the big hubs, because the onward journey means finding a named driver in a car park rather than following a sign to a platform. Buy an eSIM before you travel; there is wi-fi in the halls if you have to set one up after landing. Cash machines are landside in both terminals, and small notes are worth keeping for the road.

If a long wait is unavoidable, spend it in town rather than at the gate: the riverfront and the beach are close enough that a stored bag and a taxi buy a real afternoon, and hotels here are used to guests checking out well before a night flight and sending them back by car. Left luggage is landside, so collect it before you clear departures.
