BRIDGETOWN, Barbados – Some visitors to Barbados have been giving the Grantley Adams International Airport (GAIA) negative reviews on various websites. And they are especially critical about the attitude of customs and immigration officers. Discerning travellers are going on websites such as Britishexpats.com, TripAdvisor.com and Barbados.airport-authority.com, to name a few, to write their experiences for the world to see. “A special kind of hell” was how one British visitor writing on TripAdvisor.com last September described the GAIA.
