Looking at booking a flight with them RDU (on Jet Blue) to JFK to FRA on Friday November 21 - with the current ATC issues due to the government shutdown, I know going through JFK could be dicey. there is a super long layover (6 hours) - my main question is, in case of IROPS - what are my options? (other than the flight the next day?)- Do they have interline agreements with other transatlantic partners that could get me to FRA ? Mainly LH - it is listed on their wikipedia page as an interlien agreement (for whatever that is worth)

Just looking at options

thanks!
