This is the third change Delta has made on my flight to PDX-AMS, AMS-BUD, PRG-AMS, AMS-PDX. They have all been major changes but this one is just a delayed time. I will be arriving AMS at 8:45 and Leaving for BUD at 10:10 am. Is that enough time. I assume I can check my luggage all the way through to BUD and just go through passport control at AMS but how far away from International arrival is European local flights? I appreciate your advice.

You should be fine. And if all legs are on one ticket you will be accommodated on the next available flight if there is a misconnect.

Like most big airports, Schiphol provides lots of information on-line to help you use the place, including maps. http://www.schiphol.nl/index_en.html

They have changed ours 3 times as well. From JFK-Barbados in February. It must be common with this airlines.

We've had two changes on American in the last three weeks. Kind of screws with schedules, but we were able to change the flights to accommodate our existing reservations on the ground at no cost. Actually got better flights that what was available when we purchased (at least at the price we paid) and shortened the overall layover time.
