It is correct that Allegro Air is a Mexican charter airline. This company have no relationship with the Hotel chain with the same name.This airine is used by many american Tour Operators to fly their passengers to different destinations. Most of the charter airlines usually offer a friendly service on board and the fact of delays is not something you should take as a regular problem.Since this flights some times are not regular departures,as it is the case with schedule airlines,it is possible that the departure times assigned by the airports for that particular flight is exposed to some modifications. The charter flights are a very good way to travel to the Dominican Republic specially taking in consideration the hight airfares offered by some regular airlines that are only interested in making money with the ethnic travellers (Many dominicans in the USA!!!) that are obligued to pay those fares if they have to travel.Dont be afraid of these charter flights.
