I'm trying to coordinate FF tickets on two different airlines and my son and I may need to fly into Aruba on Delta on a Sunday. Getting to Bonaire from there seems particularly difficult on that day. One airline with a flight that works better for us than DAE is Tiara Air to Curacao, then DAE or Divi Divi to Bonaire. Does anyone have any experience or knowledge of them?

Both Tiara and Divi Divi have said by e-mail that they're going to start direct service to Bonaire sometime soon, but both were incredibly vague about it ......

As far as I know Tiara Air has only permits to fly Aruba-Curaca and the DiviDivi only Curacao-Bonaire. Both try for quite some time now to get permits to fly also the missing island, but how much longer this will take, nobody knows. I have no experience with Tiara, just heard they are reliable. DiviDivi is a great little airline !

Just returned using FF miles, next time I will pay to avoid Aruba.
Returned DAE yesterday back to Aruba then to US.
Our trip to Bonaire was delayed departing AUA but since we didn't have a connection - no problem. However yesterday was a different story.
A bus takes you from the terminal to the plane at AUA and there was a long delay as they off loaded a person in a wheel chair. The luggage was also delayed and since there is no baggage agreement and you must claim your baggage then re-check in the clear customs, 2 immigration and 2 security checkpoints. We almost missed our plane. So I would advise a 3 hour Aruba layover at a minimum when returning.
Also search the threads regarding departure taxes as being informed will save some $$
