also be careful cause your layover is very short

i dont know if these two hours are between first flight landing and second flight boarding time .

to summarize

- exit = depends on arrival gate you can be very far from exits, or a bus will bring you to exit and both can take a while
- check-in = for DL flights i guess they have dedicated counters , but they are not flying small planes over atlantic
- security = if you have access to skypriority sometimes it can save your a$$ because of queues
- passport control = depends on the time of the day there are huuuuge lanes in amsterdam , (one case i had to wait 40 mins)
- TSA = flights to USA require extra screening (if i remember correctly in AMS you need to pass through D1 gate)

Of course i havent mentionned any possible delays . Even if each step takes 15 mins (you will be very lucky) , it mean you will be just on time

so if i was in your case i would really consider the risks and if it is worth the price to check a bag in AMS

In order to do such things , 2hours are enough only between two schengen flights
