Your rollerbag and backpack will go in the rear baggage area below passenger luggage. Anything additional like a cooler or headset bag needs to go under your seat. When airlining you are allowed to check your bag as long as everything you need to fly is on your person (uniform, headset, documents) in case your luggage is lost. When I bring my cooler I use it for extra little snacks that I get at the hotel like fruit or yogurt. The only time I really go to the store to fill it up is when I've got an overnight trip to the Bahamas or one of the islands further south. Food is ridiculous expensive down there.
