travel taxes

Do you mean the Air Passenger Duty?

In the lowest class of travel offered, from Edinburgh APD at the reduced rate is charged @ £13 for a destination under 2000 miles and £78 for one over 2000. In a higher class it is £26 and £172 respectively.

However, it is the all-in price that ultimately you pay of course.

Yes, I guess I am confused. Is that not just priced into the ticket you buy? Price a ticket from the US into EDI with return and the cost is the cost, or are you expecting a toll booth or similar as you enter the airport to depart?

It is included in your airline ticket price. Look at your airfare. It will show a breakdown of taxes and fees. If you haven’t bought your ticket yet, just go to your airline’s website and search for flights to see prices.

This is not something you pay separately. It is paid when you buy your ticket.

The reason I asked I retired from the airlines and just pay tax

The reason I asked is I retired from the airlines and only taxed on the miles and billed separately for departure I'm flying standby There isn't a paid ticket

Well, then that explains the question much better. Marco indicated the cost, still very reasonable I think for the UK, I think in general you would not find much less, of course London Heathrow is much more.

The UK government has a webpage with all the figures for this year and next year.

There is no difference in amount for APD in any of the main airports - only those in Northern Ireland and the Scottish Highlands and Islands region are different. There is a difference depending on the class of the flight.

What does differ is the airport's passenger service charge.
