Flights within Europe are not that heavily taxed, otherwise I wouldn't be able to fly Berlin - Brussels for 9 Euros.
For comparison, I had a vehicle breakdown and needed to take an (awful) bus that distance in the US, and it cost far more than $23 (IIRC, it was ~$75 and took 18 hours).
It isn't: Air Berlin, Monarch, Primera, Small Planet, Azur, Cobalt, VLM, PrivatAir, Icelandic carrier WOW.
Primera and WOW were in trouble because they couldn't offset losses on their long-haul with anything.
I mean... I will not consider lower confort on transatlantic route, while sub 3 hour flights Ryanair is actually great.
Though even at profitability, the flights in EU are typically cheaper.
Flights in Russia, Ukraine, Belarus are very expensive... They are in Europe as well.
How is it so low? Even with all subsidies, kinda hard to believe
As with many things, the game with taxes is how to make the incidence of the tax fall more on the consumer and less on the producer. If you can accomplish that, then the tax is more likely to get through because unfortunately we don't have consumer lobbyists anywhere as strong as the business lobbyists.
I used to be a great proponent of Norwegian... but now... They cost as much, with less flexibility.

Basically, if demand for a product is inelastic (eg. cigarettes, insulin) that will pretty much be 100% passed on to customers by the business. You can see the supplied link for examples where the seller has no choice but to eat the tax (or most of it) or people will just stop purchasing.

The rest are actual charges that airports/government services levy for work done, as well as the famed fuel surcharge (usually recently noted as international/domestic surcharge) that airlines use as an wildcard addendum to the base fare of the ticket.
APHIS User Fee USD 3.96
Immigration User Fee USD 7.00
Customs User Fee USD 5.77
United States International Departure Tax USD 18.60
United States International Arrival Tax USD 18.60
Passenger Civil Aviation Security Service Fee USD 5.60
Air Transport Tax USD 46.58
German Aviation Security Charge 19.15
The majority of the charges are airport services. But they typically just put everything with Taxes, so you think it's taxes.Thats insane revenue, you would expect at least a good service from it.
In Germany consumer electricity prices have a comparable fraction of taxes and fees. So do salaries for high-paying jobs. If these levels are tolerable we can certainly go higher.
