We travel full time, book a lot of travel, and write/research about budget travel. Therefore I literally came up with 75+ websites that I actually and regularly use. This isn’t just about miles and points, but about resources for budget travel and travel in general.
Sure there are other tools that other people will find helpful, but I easily came up with over 75 that I found helpful. Booking websites to phone apps. Here’s what we use/check on a regular basis. Bookmark this page and you’ll never have took bookmark again. 
Booking cheap travel
BlaBlaCar.com
Carpooling website in Europe.
Carpooling.co.uk or carpooling.com
Carpooling website in Europe.
skyscanner.net
For searching european discount airliners (especially in Europe) – SkyScanner also has an “Everywhere” feature, and a general country feature. I could type in “United Kingdom” for the departing airport, and “everywhere” in the destination airport, then I can select flexible dates and search for the cheapest flights around.
megabus.com
US and western Europe buses for as low as $1.
Kayak.com/explore
Gives suggestions for cheapest flights (google.com/flights kind of does the same thing).
Hipmunk.com/hotels
Searches hotels and gives maps of hotels and landmarks so you can pick the best hotel.
matrix.itasoftware.com
For paid miles earning flights, this is the best possible resource for searching flights. Searching specific airlines, connections, multiple airports and ranges of dates and open-jaws. See How to Use ITA Matrix.
AirAsia
For discount flights in Asia.
Google maps public transit
Autoslash
Discounted car rentals.
couchsurfing.org
Lend a couch, borrow a couch, or meet ups. Haven’t “surfed” in over a year, but when we had a couch we hosted a lot of people.
CheckMyTrip.com
I use it in two ways. The most common one is checking flights I booked on OTA’s… by which I mean mistake fares. And sometimes I use it to find the “fare basis code” which you need to know for earning miles a lot of the times. Read about Booking Class Codes here.

Physical things to travel with
International outlet adapter
Monster To Go power strip (choose between 4 outlets, and 3 outlets and 1 usb)
This is a beautiful thing. We have one power converter that goes from most outlets to an american outlet. Then with a short chord it goes to 4 outlets.
My Passport Ultra 2TB
You need a harddrive that’s not only small, but self powered. So this is the best bang for the buck in all kinds of ways… it’s 2 terabytes.
GoPro Hero 3+ Black (the best video camera for travelers).
FreedomPop Mobile Hotpot
Once you buy, it’s $0 a month if you stay under 500mb of data. Bus rides, cars, airports… there are so many times this comes in handy. It needs Sprint wimax (4g).
FreedomPop Phone
Same thing, 500 text/month, 200 minutes of talk/month, and 500mb data/month and it’s completely free. It needs Sprint wimax (4g).
Truth be told, mine just got lost/stolen. So now do we get another one, go without or add to tmobile?
T-Mobile Unlimited Data and Text in 120+ Countries
Tmobile gives unlimited data and text internationally, and you can use google voice to do unlimited calls internationally. It’s $50 a month but the family plans are very reasonable. So if you can find a family to tack onto, another plan is only $10 more. Also, if you use the refer a friend (go back and use my name in the refer a friend link (Drew Macomber)), you get the unlimited plan.
Conclusion
My goal was to add 100 resources, however, this is all I could think of going through my history. Any other suggestions? What should I be using? Obviously I know about expertflyer, KVS and other premium tools. I have no interest. But what are some others? Particularly free tools you think I’ll enjoy.
