from my experiences - allow yourself plenty of time to complete the security checks (which are thorough but not unreasonable - there is a pre-check and luggage scan before check-in) but check-in doesn't open until 3 hours before departure IIRC so try to aim to get there about 3 hours before you flight. I got there a little too early and had to wait for check-in to open. Otherwise its not really much different to any other airport. The DAN lounge is nothing great but nice enough to wait in.

Stock up on some Israeli wine in Duty Free, we bought some fantastic purchases that I cant find here
