First time flyer here. Im looking to a book a flight that I am unsure of and just wanted to know if this layover gives me enough time. The flight would be United Express from Ottawa to Newark and United Express from Newark to Fort Wayne with a 45mins layover in Newark. My question is if I do a pre clearance in Ottawa (Canada) will I bypass customs in newark? and will I need to recheck my baggage or will it go all the way to Fort Wayne since both flights are United Express? Also would it be difficult to make my connecting with 45mins?
