It's an international flight, so the price is more expensive relative to a flight between two US cities. Usually it's 300 USD to fly compared to 140 USD by rail. Two things to keep in mind by rail to Montreal: customs add 1h, and in summer, if the rails are too hot, per Canadian regulations, the train cannot go faster than 50km/hour or something ridiculously slow like that, which adds another hour or two. Onboard wifi only works when in the US, and because of the mountains in upstate NY, the signal can be very flaky and slow.
