Union Island International Airport (UNI) Guide: Union Island, Saint Vincent and the Grenadines

Union Island International Airport is a tiny Grenadines airfield for one of the Caribbean’s more beautiful small-island arrival experiences. UNI is useful in concept, but it is not a broad scheduled-airline airport. Many travelers reach Union Island by ferry, charter flight, water taxi, or yacht rather than relying on a frequent public timetable.

This guide is written for travelers who want the useful details first: the real airport name, where it sits, how much to budget for transport, what to expect in the terminal, where to search for flights, and which services to arrange before landing. Prices and routes are updated for June 2026 and should be treated as practical planning ranges rather than fixed promises.

Quick airport facts

• Best for: Union Island, Clifton, Tobago Cays access, kiteboarding, small guesthouses, yacht charters, and Grenadines island hopping.
• Main route logic: public scheduled services can be absent or very thin; charters and inter-island operators matter.
• Airport style: very small island airport with minimal services.
• Planning rule: confirm the operating flight or charter directly, then confirm the boat/ferry backup.

Address and location

Use Union Island International Airport (UNI) for flight searches and Union Island Airport, Clifton Airport, UNI Airport as backup search wording in maps, hotel messages, and taxi conversations. The practical address is:

Clifton / Union Island, Saint Vincent and the Grenadines; coordinates 12.600135, -61.411945.

Very close to Clifton village, usually 5-10 minutes by local taxi or a short drive to many guesthouses and docks. For a serious itinerary, save the airport coordinates offline, download the city area in Google Maps or Organic Maps, and keep your hotel address in both English and the local language where possible.

How to get from the airport to the city

Union Island is small enough that the transfer is not the hard part. The hard part is confirming how you get on and off the island if the flight, ferry, or weather changes.

Transport tips

• 🧾 Confirm the fare before loading luggage, especially when there is no visible meter or posted rate.
• 📍 Save the exact hotel pin offline; airport drivers may know districts better than street names.
• 💵 Carry small local cash for the first transfer, baggage carts, snacks, or phone calls.
• 🌐 Install an eSIM before departure so you can message your driver immediately after landing.

Public transport and metro

Union Island has no metro, airport rail, or city bus system in the usual sense. Use taxi, guesthouse pickup, walking for nearby stays, ferry, or water taxi.

Where public transport exists, it is usually best for daylight arrivals with light luggage. For late flights, family travel, heavy bags, or first-time visits, a taxi, hotel transfer, or pre-booked private driver is usually worth the extra cost.

Taxi prices and transfer strategy

Taxi prices around airports are rarely as neat as an official table. Time of day, luggage, driver availability, fuel prices, and whether the destination is inside or outside the central city all matter. The ranges above are realistic planning budgets, but the best practice is simple: agree the fare before moving, keep your phone map open, and avoid changing money with random drivers.

For smoother arrival logistics:

• 🚕 Use official taxi ranks or a hotel-arranged driver where available.
• 🧳 Pre-book a transfer if you land late, carry equipment, or travel with children.
• 🚗 Compare rental cars before arrival with DiscoverCars if you need regional freedom.
• 🏨 Use Expedia to check hotels near the airport and in the city before choosing a transfer.

Airport facilities, shops, and restaurants

• Very limited airport facilities: basic check-in/security style processing when flights operate, small waiting areas, taxis, and nearby village services.
• Do not expect major retail, lounges, or full restaurant choice at the airport.
• Carry cash, water, sunscreen, and printed accommodation contact details.
• Small aircraft and boats can both be weather-sensitive.

The smart rule at UNI is to treat the terminal as a transfer point rather than as a shopping destination. Eat before arriving when possible, keep a refillable bottle where security rules allow, and bring a small power bank. If you have a long delay, an airport-area hotel or city hotel is usually more comfortable than waiting in the terminal.

Airlines and where the airport flies

Public route tools may show no regular scheduled passenger destinations from UNI on many 2026 searches. Travelers should check SVG Air, local charter operators, ferry companies, and guesthouses for the current practical way to reach Union Island.

If scheduled or charter flights are operating, small Grenadines operators such as SVG Air-style services are the first place to check. Otherwise, route through Argyle (SVD), Barbados, Grenada, or nearby islands and continue by ferry or charter.

Cheap routes to check first

• Compare Union Island ferry or water taxi options with any available charter flight.
• Use SVD, Barbados, or Grenada as broader gateways before the last island leg.
• Avoid tight same-day international connections after a small-island hop.

Cheap airport strategy is different from simply sorting by lowest fare. Always compare the final cost after checked baggage, seat selection, payment fees, transfer costs, and missed-connection risk. A slightly more expensive flight into the correct airport can be cheaper than a low base fare that forces a long taxi ride or overnight hotel.

Where to buy flights and hotels

Start with broad searches, then verify the exact airport code before paying. This is especially important in cities with more than one airport or with airport transitions.

eSIM, internet, insurance, and car rental

• 🌐 Internet: install Yesim eSIM before the flight. Airport Wi-Fi can be slow, blocked by SMS verification, or unavailable exactly when you need maps.
• 🛡️ Insurance: compare policy wording with SafetyWing. Read exclusions for the destination, adventure activities, medical evacuation, political/security events, and pre-existing conditions.
• 🚗 Cars: compare vehicles on DiscoverCars before arrival. Airport counters can run out of automatic cars or quote higher walk-up rates.
• 🎟️ Tours: use Viator for airport transfers, city tours, day trips, and guided experiences when independent transport is inconvenient.

Practical arrival checklist

Safety and travel notes

The eastern Caribbean is generally straightforward for visitors, but airport transfers, ferry schedules, tropical rain, hurricane-season disruption, and cash-only local transport can complicate short itineraries. Use licensed taxis or hotel-arranged transfers at night, keep small local or U.S. dollar cash, and buy travel insurance before island-hopping. Small-island travel adds weather and boat-transfer risk; do not cut the return to an international flight too close.

The most reliable traveler is the boringly prepared traveler: documents printed, data working, transport confirmed, hotel address saved, and enough time between every moving part of the itinerary.

Short airport excursion idea

If you have a long layover or an overnight stop, choose one simple plan rather than trying to see everything. Stay close to the city center or a known hotel district, keep the return transfer booked, and avoid cutting the return to the airport too close. In smaller airports, a missed flight may mean waiting a day or more for the next practical departure.
