Thomson actually operated to Orlando and Dom Rep in 1996 and 1997 after the runway was lengthened - and loads were 100%. Never understood why they didn't continue it.
Change of policy - they dropped those flights from all regional airports including HUY
Good news they are doing this again although why Do Rep is in the list instead of higher demand Barbados and Orlando I don't know
AFAIK the La Romana flights are to connect with cruises that depart from there
