Looking to get from JFK to London Airports on a budget

Hi there,

I'm in a situation where I need to leave my home in New York and head to London on a one way ticket.

However, I only have a small budget (roughly $800) and I need to travel ASAP.

I don't mind doing connecting flights and small lay overs.

I've been looking at taking an Aer Lingus flight from JFK to SNN, and then getting a RyanAir flight from SNN to STN. If I book for a week or so from now, I seem to be able to get these flights at quite a good price. However, I am worried that the 1 hour gap between my flight from JFK landing, and my flight to STN taking off, will not be enough time.

Any and all help is appreciated!
