First, if you have any flexibility around your destination, you can put in your home airport and put "Europe" or "Anywhere" in the destination field and then you can pick depending on price. I use this a lot, as you can easily get from one place to another using regional transport or trains once you are there (which I will discuss more below).
Next, it may make sense to put in multiple airports in either the to or from field. To do this you just click the plus and add any airports you want to check. In my case, I could go from SFO, but it may make more sense to fly from LA (LAX) for some destinations. If it is a significant difference, you can get a cheap flight on Southwest or whatever the local carrier is and possibly save money without sacrificing time. If you have a lot of time, you can even use further locations and you may even be able to have a couple of fun days in a new place! You can also check "San Francisco area" instead of San Francisco and it will automatically search from San Jose, Oakland, SFO etc.
Doing this for a trip to Berlin, it was $400 less to go from LA, and a Southwest flight from Oakland to LA is only about $200. If you don't have the time or the patience for this, I understand! However, if you do, it could work out well. Also if you live in a small town or city, it may make more sense to choose some larger cities and then get to the airport on a separate flight or drive.
I recently looked into flying from SFO to South America. From SFO to Buenos Aires it was about $500-$900 one way on Avianca, but if you go from Miami, it is $300, and you can get a flight from SFO-MIA for $90 on Frontier or $84 on Jet Blue (including one carry on). That is a savings of ~ $110 - $510 each way depending on which one you choose! Sure, it may take more time, but you could go a couple of days early and experience Miami too.
Speaking of carry on, when I search for flights, I always put a few things into the filters. First, put your luggage in; this will edit the price for airlines like Frontier, where if you do not put this in, the flight looks cheap, and then you add your options (choose seat, luggage, etc.) and it is not as great of a deal. Just beware, as this will add the cost of baggage for some, like Frontier or United, but not for others, like EasyJet.
I also sometimes deselect some of the connecting airports. If you have ever transited through Chicago O'Hare or Washington Dulles you will know what I am talking about, as some airports are a pain to go through, especially for international flights.
Speaking of that, for all flights, but specifically for international ones, a couple of other things I watch for are layover time and connecting airport. If you have to go through customs, I would suggest a minimum layover time of an hour and a half, just in case. I once had a 50 minutes in Frankfurt and even though I only carry a backpack (no rolling luggage) I was sprinting and sweating to get to my flight on time. I don't know why they do this, but I would check that closely!
For connecting airport, here is the rub. Let's say you are flying from Berlin to San Francisco. If you transit in Frankfurt, you will have to go through the European exit customs in Frankfurt, so you will need extra time there. If you fly from Berlin to JFK and then to San Francisco, you will go through the European exit customs in Berlin, and the US entry customs at JFK. This can pose a problem as well, as you may have to retrieve your luggage and put it back through security at this point, so you will need extra time. This is yet another reason to only travel with carry on. Personally I would rather transit in Europe and skip a US layover, and go through customs when I get to SFO, so I plan my flights accordingly. Or even better, I buy a non-stop flight. Sometimes the extra cost is completely worth the decreased hassle factor.
Speaking of non-stop flights, just as with the departure city, sometimes it makes more sense to get a non-stop flight to whatever major city is cheaper, for example, SFO to Frankfurt, which can be cheaper and saves issues with transiting and customs, and then taking a regional flight or a train or a bus to wherever you want to go. At the time of this writing, round trip flights in January from FRA to either Marseille, Krakow, Barcelona or Seville cost around $200.
Last, but not least, if you have flexible dates, you can look at the price or date graph, and you can toggle the "track prices" button to get emails when the price changes.
Actually, THIS is last, but I never book through Google Flights or Expedia or Orbitz; I always go to the specific website for the airline. I also don't book one leg with one carrier and another leg with another, as I have done this in the past, and when one flight is delayed or canceled, it can be a rescheduling nightmare. The good thing about Google Flights though is that you can click through their site to book the flight on the carrier website once you have decided which flight you want.
I think that is everything! Let me know if you have any questions or want more information. If you are new here and you want to see where I've traveled so far, check out my Around The World page!
Also, tell me: What website or method do you use to find good deals on flights?
