Tips to save money on airfare

1. Kayak

Use the app Kayak to create a price alert. This will tell you when the price of the flight tickets goes down.

2. Time frame to buy the flight tickets

 Buy the the flight tickets between one month and two weeks prior to your desire date of travel. This works because if the airplane it's empty the airlines will lower the cost of the tickets.

3. Check if your desired flight it's full o empty

I use Orbitz for this. You only have to select your desired flight on Orbitz and it will appear the option to select seats with this feature you can see how the sale of the flight it's going.

4. Buy the flight tickets at night

The best time to buy the flight tickets is between 6 pm to 7 am.

5. The best days to buy the flight tickets are Tuesday, Wednesday, Friday and Saturday.

Cave of Wonders ( Cueva de las Maravillas) Dominican Republic

The Cave of Wonders is located on the road between San Pedro de Macoris and La Romana. It has paintings and engravings on the walls made by the Tainos Indian. The tour is given for about 300 meters inside the cave and 25 meters underground. The tour ends visiting a sanctuary of iguanas. The price of the ticket is 300 Dominican pesos or about $6.50 dollars. I recommend you to visit the cave if you are near by because it has beautiful paintings and engravings that are part of the history of the country and you can only see them in person because they don't allow you to take pictures of the paintings and engravings.
