Using the example of the Capitol Limited, it is clear the multiples are out of wack. For instance, an end to end, Chicago to DC trip:
3/24: $98 seat, $264 roomette, $498 bedroom
3,381 pts seat, 9,108 pt roomette, 34,362 pt bedroom
3/25: $98 seat, $325 roomette, $400 bedroom
3,381 pts seat, 22,425 pt roomette, 13,800 pt bedroom
For certain trips, it is arbitrarily doubling the number of points necessary - when the fare goes above a certain bucket, or for dates that Amtrak doesn't like. Southwest does something similar with their ranges (anywhere from 55-80 points/dollar depending on fare bucket), but not to a 2X level. Why have a "fare calculator" before implementation when AGR doesn't observe it?
