Took the budget airline Easyjet from Paris to Nice and tried Orly Airport this time. In general, Orly Airport, just like CDG and Heathrow take a much longer time for all those check-in and security check; so sparing 2 hours may not be enough. As I didn't expect the check-in and security to be very slow, I didn't have time to check out the south terminal of Orly Airport. Just went thru' straight to the boarding gate after the security.
On board Easyjet, we chose to buy their meal set for a sandwich, chocolate or chips, with a drink at Euros 8. Got a sun dried tomato and mozzarella cheese sandwich. Unexpectedly good even though it's a vegetarian sandwich.
