Honestly, the best thing to do is get an airline's credit card - if you got the credit - and rack up miles with whoever you want to fly with for the majority of your travels. Think of international airlines like United, Delta (known to be the constant best), JetBlue, British, KLM, and Lufthansa. There are better airlines like Singapore, Qatar, and Japan to name a few, but I don't know much about their destinations compared to Delta or British, which tend to go everywhere.
Yes, here are some deals that transpired last Black Friday and there are some others that happen on Cyber Monday. These tend to be part of each individual airline and these are days you know that deals will happen. The problem is anybody can get deals for airline tickets at any time of the year, but you gotta keep chequing constantly because it changes all the time. It is a very fluctuating industry and sometimes booking a year in advance gives great deals, while others are a week before. Google Flights is needed because it shows the best price among all the airlines. There are some trends you can eventually spot, early or late flights tend to be cheaper than mid-day flights (red eye tends to be the cheapest).
It is based heavily on supply and demand, but some cities are easier and cheaper to travel into. For example, travelling to Poland is very expensive, so a lot of Polish people that moved to the States or Canada tend to fly into Germany and take a train because it is almost 500 to 1000 dollars cheaper. Additionally, the time of the year can also very heavily affect the price like going to Rome or Napoli in August is a lot cheaper than going there in May. Going to London is a lot more expensive in June or July than in November. Nonstop is much more expensive than stopping once or twice, but nonstop might be more worth it due to decreasing jet lag and decreasing the chances of losing your luggage if you need to cheque bags in. Personally speaking, almost 95% of people I've seen recommend carrying light and only use carry-on bags even travelling from Europe to NA or vice versa.
E: Also Google Flights has a price calendar that shows ticket prices for your destination so you can figure out if that price is currently a good deal or if it is the norm.
Act fast for some great Black Friday travel deals, from a $2000 round-trip business-class ticket to Paris to bucket list trips to Antartica or the Galapagos.
