how far is Amsterdam airport to Newcastle?

I assume you mean by plane because by car/coach it would also depend on which ferry you took (Newcastle -> (close to) Amsterdam, Hull->Rotterdam, Harwich-> Hook of Holland, or one of the many routes by ferry/tunnel from Dover to France or Belgium

So by air (direct flight) it is between 1hr15mins and 1hr25mins depending which way you are flying http://www.ebookers.nl/afo/flights/step2.html?VERSION=NL&LANG=NL&from_wait=19521&SID= SDakDQrfNG0AAAvQ3M4&

The airport of Amsterdam (Shiphol) is in the Netherlands, Newcastle in UK.
