Cheapest time/way to book flights to Nashville within the US?
So I already have a return flight from the UK to Boston in October, and am hoping to book an extending flight from there to Nashville for a long weekend.
I was just wondering when would be the cheapest time to book flights like this, am I better off waiting til much closer to the time? Are there any particular websites or apps that are good for cheap US flights?
Any advice would be really appreciated, as well as any other sub recommendations that might be better for this type of question – I wasn't really sure where to post but figured here would be as good a place to start as any.
