Hi
I have recently been travelling across the USA and from New York to Washington DC, I would 100% recommend Amtrak instead of flying. Reasons being -
1. Amtrak you get wide seats and the ability to walk around - super comfortable.
2. You can arrive at Pennington Station in downtown NY (great if you are staying at Times Sq like I was) about 15mins prior to your train departing and get on.
3. Train trip to Washington was only 3.5hrs.
In addition, my travel agent got me cheap tickets (once I paid some joining fee - approx $40) for the train. It was approx $208 AUD (inc joining fee) for 2 people via train to go NY to Washington one way. It was cheaper than their website once you had converted.
Also, don't buy the Express Train tickets since they cost almost double and are only 20 mins faster.
Whenever I catch domestic flights in the US I allow 2hrs for check-in so by the time you factor that in with the flights and getting to & from the airports the train takes about the same time.
American Eagle flights are OK but the planes are cramped since they use small twin prop aircraft.
From a person who loves to fly - try the train as you won't be disappointed.
