If you're looking for a less-visited Caribbean destination, Trinidad and Tobago may be a pleasant surprise. Air Canada offers flights to the capital city of Port of Spain departing from Vienna for 535 eur.

Return tickets are available between January and March.

The flight is operated with one change in Toronto. On the way there, the transfer time is 4 hours and 45 minutes. On the return journey, the layover is approximately 11 hours - you arrive in Toronto at 7:20am and the connecting flight to Vienna doesn't leave until 6:30pm, which can be used for a short city tour.

Cabin baggage and a small personal bag are included in the ticket price.

Please note that the transit is through Canada and therefore an eTA is required. This is required even if you are only staying at the airport. The fee for the eTA is 7 cad.
