| Attribute | Detail |

| IATA / ICAO | UBP / VTUU |
| City / country | Ubon Ratchathani, Thailand |
| Direct destinations (catalogued) | 0 |

| Based hub carriers | Thai AirAsia, Thai Lion Air and Nok Air |
| Coordinates | 15.251, 104.870 |
Coordinates are for checking, not decoration. UBP sits at 15.2513, 104.87. That is genuinely useful when booking a room or a transfer, because “near the airport” is claimed to wildly different standards. In a large city, map distance and real travel time in peak hours diverge sharply — read the travel time for the hour you will actually move, not the kilometre figure.
IATA and ICAO are used in different places. The three-letter UBP is the IATA code that appears on tickets, bag tags and search screens; VTUU 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.
Airlines serving UBP
4 carriers appear at UBP in our catalogue and we hold an airline row for 4 of them, with baseline baggage spanning 7 to 15 kg. None of the rows we hold sits in a major alliance. 3 of them are based here.
| Airline | Alliance | Baggage | Role |
|---|---|---|---|
| Thai AirAsia (FD) | non-aligned | 7 kg | hub |
| Thai Lion Air (SL) | non-aligned | 15 kg | hub |
| Nok Air (DD) | non-aligned | 15 kg | hub |
| Thai Vietjet (VZ) | non-aligned | 7 kg |
The 7–15 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.
“Serves” is not “flies daily”. This list covers every carrier appearing on a corridor into or out of UBP 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.
UBP route overview
UBP has 0 outbound corridors in our catalogue, roughly 0 departures a week All figures are estimates of the standard schedule. The field runs on Asia/Bangkok, ICAO VTUU. The corridors touching this field connect 1 country in our catalogue. Block times on those corridors run from 1.1 to 1.1 hours.
Inbound
| Route | Freq/wk | Hours | Market low |
|---|---|---|---|
| Bangkok (BKK) → Ubon Ratchathani (UBP) | 28× | 1.1 | — |
Outbound and inbound are asymmetric because this is a catalogue boundary. We record 0 outbound and 1 inbound corridors for UBP. The gap reflects which route guides we chose to build — weighted to what travellers from Thailand search — not one-way service. The return flights exist whether or not we have published a page for them yet.
This field sits in our catalogue as a destination. We record 1 inbound corridors into it, splitting 1 short-haul (<4h), and no outbound guides — we build route pages only for journeys starting in Thailand. Departures from here exist; they simply have no page in this set yet. Read the carrier’s own schedule for the return.
Corridors & fares from UBP
The 1 corridor at UBP break down as 1 short-haul (<4h), serving mainly ASEAN & regional leisure. We hold a cached fare for 1 of 1 route, the lowest ฿2,089 on BKK–UBP. The corridors touching this field connect 1 country in our catalogue.
Most UBP corridors here serve ASEAN & regional leisure travellers. The mix is 1 short hop (under 4 h). 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.
Why some rows have no price. We capture lows in passes, and not every corridor returns a value each time. Seasonal routes, thin routes and routes sold through narrow channels report irregularly. An empty cell means no capture succeeded in the latest pass — not that the route is closed or expensive. We leave it blank rather than interpolate, because plausible-looking estimates are exactly what makes a table untrustworthy.
Direct flights to UBP — 1 route
Our catalogue records 1 inbound corridors into UBP from 1 country, block times 1.1 to 1.1 hours. Frequency figures are estimates combining every carrier on the corridor. The field runs on Asia/Bangkok, ICAO VTUU. 4 carriers appear at UBP, 3 of them based at the field.
- BKK → UBP — 28×/wk, 1.1 h, low ฿2,089
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 1 corridor 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.
Time zone and connecting at UBP
Our catalogue records 0 outbound and 1 inbound corridors here. UBP 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.
Offsets make overnight flights deceptive. With UBP 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.
Minimum connection time is not in our data. Every airport publishes one, and the figure differs for domestic-to-domestic, international-to-international and terminal-change connections. A booking system will not sell you less than that on a single ticket — but it will happily let you build less than that yourself across two tickets. That is where passengers most often create risk without realising it.
