​Airfare

Momondo :
Possibly the most accurate flight search engine available on the net. I cannot book a flight without checking here first.

They have a great feature that shows both regular flight prices and low cost.

Sometimes, I can save up to 60% by booking a low cost flight. And you should too.

Expedia:

One of the oldest services that have everything from hotels and car rentals, to flight recommendation. 

However, since I only use them as a flight search engine, I can recommend them for that. But be sure to check out the rest.

Hotels

Booking. com

My go-to website for booking a hotel room. They have all the best deals on the internet.

Many other websites have tried to compete with Booking.com but they all fell short.

They have the best service for looking for the best hotel deals that match your needs.

airbnb.com

Many travelers love to get in touch with the locals rather than stay at a hotel.

Airbnb is exactly what you need if you are one of those travelers. You will many local hosts providing comfort at the cheapest prices.

If you need a travel group, you just have to book a shared room and you will meet travelers looking to share the experience, too.

Tour Companies

Interped Travel

If you are looking for small group tours, INTERPID is the best in that department.

They have multi-day tours for small groups and they are all led by experts.

The price is not at all expensive considering how much learning and discovery you'll make with them.

Transportation

Rome2rio

" How to get from point A to point B? " That's the most asked question in any trip planning.

Rome2Rio provide accurate and cheap answers to that question every time you use their services.

They compare time and prices for all companies and means of transportation available to give you the best deal.

Insurance

World Nomads Travel Insurance

Every traveler needs insurance and this company is the best at that.

It is safe to assume their high quality service since they are recommended by National Geographic.

You can check on your insurance with them any time as they have a great customer service.
