Flying in to Tobago airport you will find minimal facilities with x-ray or your baggage being the norm (you'll wait a while for your cases!). The experience when flying back out was underwhelming. The 'check in' area is outside the main building in the heat long queues and staff who are happy to chat to eat other mill about and lack any kind of customer service. You'd expect that 'departures' is open all the time. Nope. Again you have to wait outside with no aircon - just a ceiling mounted fan just outside the entrance - and wait until the staff decide they're ready/bothered to 'open'. The best I can say is that the grunts of communication were followed up by pointing at what you needed to do and where to go. Appalling and very slow. The departure lounge itself has air con but the plastic seats (part of the airport upgrade!) are shockingly uncomfortable. If you want duty free shopping you're limited to a small shop about the size of a single bedroom with vodka rum and a few bits and bobs a perfume/soap shop and souvenir stall with t-shirts keyrings and beach bags. There is a small counter area where you can buy drinks and snacks (this is not Costa). You may be sad to leave Tobago but the airport will encourage you to get on your flight.
