Hat Yai International Airport (HDY, ICAO VTSS) is in Hat Yai, Thailand. It is the based hub of Thai Airways, Thai AirAsia and Thai Lion Air. In the SiamFlights catalogue, HDY is served by 7 airlines across 5 routes (4 outbound, 1 inbound).

Airport at a glance

Our catalogue records 4 outbound and 1 inbound corridors at Hat Yai International Airport (HDY / ICAO VTSS), serving Hat Yai, Thailand, across 7 carriers with 3 of them based here. Time zone Asia/Bangkok. Frequency across the corridors touching this field totals about 82 departures a week.

IATA and ICAO are used in different places. The three-letter HDY is the IATA code that appears on tickets, bag tags and search screens; VTSS is the four-letter ICAO code used in flight plans, notices to airmen and operational paperwork. IATA codes can collide for historical reasons; ICAO codes do not, and their first letters encode the region. A four-letter code in aviation documentation is not an error — it is a different system.

A base changes the outcome when things break. Thai Airways, Thai AirAsia and Thai Lion Air are based at HDY, meaning aircraft, crew and operations staff sit on site. When a flight is cancelled the odds of a seat on the next rotation, or of a spare airframe, are far better at a base than at an outstation the carrier touches once a day. It is why the leg departing an airline’s own base usually recovers faster than the one returning to it.

Airlines serving HDY

7 carriers appear at HDY in our catalogue and we hold an airline row for 6 of them, with baseline baggage spanning 7 to 46 kg. Alliances present: SkyTeam, Star Alliance. 3 of them are based here. Block times on those corridors run from 1.3 to 10.5 hours.

“Serves” is not “flies daily”. This list covers every carrier appearing on a corridor into or out of HDY in our catalogue. Some fly seasonally, some a few times a week, and some sell as the marketing carrier on a partner’s aircraft. The number that matters to your plan is how many actually quote your dates — usually fewer than the full list.

The 7–46 kg range is two business models under one roof. The low end comes from unbundled fares that sell hold baggage separately; the high end from full-service carriers that include it. At the same airport those two desks price excess weight on different scales and by different methods. Connect between the two on separate tickets and a bag that cleared the first sector may not clear the second.

Outbound

Inbound

The haul mix tells you what this airport is for. Outbound corridors break down as 1 short-haul (<4h), 3 long-haul (7h+). An airport that is mostly short-haul behaves like a regional gateway where changing flights is easy and cheap. As the long-haul share rises, rotations per corridor fall and missing one costs far more. That mix describes the risk in your itinerary better than the total route count does.

Corridors & fares from HDY

The 5 corridors at HDY break down as 2 short-haul (<4h), 3 long-haul (7h+), serving mainly GCC labour & Muslim pilgrims. We hold a cached fare for 2 of 5 routes, the lowest ฿2,471 on BKK–HDY. Block times on those corridors run from 1.3 to 10.5 hours.

Most HDY corridors here serve GCC labour & Muslim pilgrims travellers. The mix is 2 short hops (under 4 h), 3 long-haul routes (over 7 h). 5 are labour-migration or diaspora corridors where extra-baggage allowances matter. Fares are shown in Thai baht (THB), and each route guide below carries live cached prices.

Everything is shown in baht, and that matters more than it looks. Fares are converted to THB so they compare on one page, but the underlying prices are set in the currency of the market that issues the ticket. The same corridor can price differently issued in different countries, and the exchange rate moves between our capture passes. Read these as a ranking, not as accounting figures.

Direct flights from HDY — 4 destinations

HDY reaches 4 direct destinations across 3 countries in our catalogue, with block times from 1.3 to 10.5 hours. Each line below carries weekly frequency, block time and the lowest fare our cache recorded. The field runs on Asia/Bangkok, ICAO VTSS.

• HDY → KUL — 14×/wk, 1.3 h, low ฿5,211
• HDY → JED — 2×/wk, 10.2 h
• HDY → DXB — 2×/wk, 7.2 h
• HDY → MED — 1×/wk, 10.5 h

How to read this list usefully. The frequency figure describes the risk in your plan, not the quality of the route: several departures a day gives you options when something breaks, a few a week means building in a spare day. We hold a cached fare on 1 of the 4 corridors here; the rest have no successful capture yet, which does not mean they cost more.

Direct destinations are not all reachable destinations. This list is the nonstop network in our catalogue. Everything else is reachable by connecting at a hub, which widens the choice and adds a point where the plan can break. If you must connect, make a single ticket the default and only split it when the saving is large enough to be worth the risk you are taking on yourself.

Direct flights to HDY — 1 route

Our catalogue records 1 inbound corridors into HDY from 1 country, block times 1.4 to 1.4 hours. Frequency figures are estimates combining every carrier on the corridor. 2 of those corridors carry a cached fare, the lowest ฿2,471. The field runs on Asia/Bangkok, ICAO VTSS.

Time zone and connecting at HDY

Our catalogue records 4 outbound and 1 inbound corridors here. HDY runs on Asia/Bangkok, the same as Bangkok. The gap is constant year-round. Every time printed on a boarding pass is local to that airport rather than an elapsed duration, so subtracting one from the other gives you the wrong number.

International-to-domestic is a full re-entry. At most airports that connection means clearing immigration, reclaiming the bag for customs, then checking in and passing security again — even on a single ticket. It takes materially longer than an international-to-international transfer. Plan around the actual steps rather than the gap printed on the itinerary.

Offsets make overnight flights deceptive. With HDY the same as Bangkok, a late-night departure can arrive the same morning or the next one on paper for identical flying time. That is the single most common reason transfers and first hotel nights get booked on the wrong date. Read the date on the final sector’s boarding pass, then confirm anything on the ground.
