How to find cheap flights
Finding cheap flights is a nice skill. Hitchhiking is a good way to get around but how can you get to other continents if you don't have oceans of time? Going by boat or ferry is often an interesting adventure by itself.
Environmental impact of aviation
Going by plane emits tons of carbondioxide, for example the typical comfortable canal jump London – Frankfurt – London emits 150 kg to 500 kg CO2 per person (see Carbon Offsetting & Air Travel. Part 1: CO2-Emissions Calculations), page 19). It is much worse than going by car on your own using a ferry. Please think twice before paying for the destruction of our climate. Even if fuel efficiency of modern aircraft is better by consuming less fuel per kilometre, the absolute amount of emissions rises by 4% per year because more people go by plane (see Are technology myths stalling aviation climate policy?).
If you still have to fly (instead of organizing in a better way), you can choose a more efficient airline, like Spirit (see Comparison of US airlines, page 8), or less consuming aeroplanes like a turboprop. However carbon offsetting is usually a scam as green labelled tropical organic farms usually grow in former rainforest areas.
- delete browser cookies and history or use incognito mode
- if you see the price goes up while you are searching, don't panic. Instead wait an hour and check again
- book in low season (november to january)
- if you see an error fare, book it (they appear in hours usually)
- be flexible with time and departure country
To search effectively, use a search engine where you can search multiple days and airports at once. Some sites allow you to search using the whole country, or all airports within a specific distance.
Sundays and Fridays are the two most expensive weekdays to fly on, in general. Some cities are however typical weekend destinations, and then the pattern is a little different. One example is Barcelona. People fly there from all over Europe on Fridays, and return back home on Sundays. Therefore, because of differences in demand it will almost always be cheaper to fly into Barcelona on a Sunday than on a Friday.
When flying, you must typically use more than one flight to get to your destination. If you travel slowly and make a stopover underway, the number of possible flights will increase. This will improve your chances of finding a cheaper flight.
The same principle applies if you during your stopover travel by bus or train to a nearby city. From there you will have additional chances of finding the cheapest flight onwards.
