I was supposed to fly DCA to LGA around lunch time today. Woke up around 7am and saw the flight was already delayed by 2 hrs+. Checked my options and got a last minute Amtrak train - Acela business class at $91 within an hour of departure was a good price - paid the same for the flight weeks ago.
Despite Amtrak being late, as usual, got in while the flight was still delayed.
