My first time flying on B6 will be this Fri (JB71 JFK-MCO) and I've got the 0615 departure, I wanted to know when I arrive (planning on around 0400) if the counters are open all night, or if I need to arrive later. I will be returning my rental to Budget on Federal Circle prior and taking the shuttle over to T4.

I plan on checking in online but will have 1 bag to check, I normally catch flights this early and most counters open around 0400 and the checkpoints are open shortly thereafter.

Any advice would be appreciated.

Thanks
