I would think that it is cheaper to fly into The Netherlands or Luxembourg or Germany but those travel sites are exhausting trying out different times and dates. I’d like to start looking with a little foreknowledge on the arrival city. Can you help?

I’m planning for a backpacking trip to western Europe (Austria, Belgium and Luxembourg, England, France, Germany, Ireland, Scotland, Switzerland, The Netherlands, Wales).How much cash do I need for backpacking trip to visit all these countries?
Hope you guys can suggest the cheapest transportation to travel around. Planning to stay 3-4 days in each countries.
