Hello, I have never flew outside the us before so I don't know what to plan for and how to make sure I don't mess up everything. So I wanted to ask here and see what everyone experience is.

Im looking to go to England from NJ with some buddy's from. More specific closer to the Nottingham area. The dates for the trip would be 13-17 of march, 2025. I know I need a passport and im gonna work on that in the next week. But I don't know what to look for with travel times and all. One website was saying it will take 16 hours with 2 stops and others say 7 which is the normal amount of time ive seen. Also don't know which airlines would probably be best for the trip over there.

Got a lot of questions but those be the main ones im concerned about. Thank you all for reading and any advice would be great and have a nice night!
