The amount and number of travel taxes, fees, and other charges added to your bill will probably surprise you. Many are hidden and like everything else, taxes keep going up.
Once in my life, I bought a round the world ticket. My experience was favorable but I think the number of times these tickets are useful for most travelers is fairly limited for the reasons outlined in this post.
I am surprised how often I can get significant improvements in convenience and comfort when I don’t buy the cheapest ticket. Often, for example, I can fly in business class from the US to Cancun for only $20-40 above the cost of the cheapest ticket. Often for a few dollars, I can get much more convenient flights as well.
Often nowadays there doesn’t seem to be that much difference between budget and traditional airlines (legacy carriers). However, unless the difference in ticket prices between budget and traditional airline is above 15%, I would recommend choosing traditional airlines for the reasons outlined in this post.
A synopsis of my experiences with finding the cheapest flights and using search engines. The article also covers many tips for finding the cheapest flights, some of which are not discussed that widely elsewhere.
I often buy tickets with a mid-price range of bundled services attached. I often think the few extra dollars are worth it. You may or may not choose to follow in my footsteps after reading this post.
