I always book airfare separately. I booked our Dec trip in Feb. I started checking about three times a week in search of the best airfare. We have found that booking directly with our selected Airline as being the best. This may not be the case if you live in a larger city. I live in a small state and in a rural setting, so this works best for me...unless I want to drive several hours and spend the night..Which generally is more costly overall.
Leaving mid week does make a difference. Booking early saved me over 300 US per person..compared to what the flight is now. Granted, I am leaving mid December....but April is also spring break for many colleges...so I would definitely start checking now. Hope this helps some. Once you start looking regularly, you will get a feel for the pricing. Try looking at some other dates to get acclimated to the charges. Good luck and enjoy Negril in April!!! One of the few months that I have never been to Negril.
