Been to Punta Cana a few times with FCA. Best of the charters. First to offer better seat pitch.
Go for the Premuim if you can afford it. Econ still fine though. Good IFE. All leather seats. Nice cabins. Food normal stuff, but it's the legroom that counts.
Give them a call and ask about emergency exits etc - details on their website at "contact us".
What hotel are you staying at?
