Sorry this reply took so long, but here's a two part answer.

• An estimate of which bucket your $1078 fare might be can be found by:
_ deducting the single Senior discounted rail fare from $1078 to find the fare for one Adult in a Roomette
_ which is 0.9 X (Coach Fare With The > Symbol)
_ which is 0.9 X $193 = $173.70
_ so the 1 Adult fare would be about $1078 - $174 = $904
_ but the chart in Post #38 only shows the two lowest Roomette buckets of $485 and $591
_ so the three other higher buckets can be estimated by adding the difference between those two buckets of $106 to $591 three times giving the five buckets of $485, 591, 697, 803 and 909.
_ The previous estimate (two steps above) was $904 and is closest to the estimated high bucket of $909, so your $1078 fare is for a high bucket Roomette.

• The actual high bucket Roomette fare for one Adult on the SWC between ABQ and CHI can be found from Arrow which shows $904 for tomorrow which is only 0.6% from the estimate. Close enough for me.

BTW, a low bucket Roomette for the two of you would be $485 (from the chart) + 0.9 X $193> = 485 + 173.70 = $658.70

This estimation method will work for any of the trips where only the two lowest buckets are given because the upcharges for the sleepers go in an arithmetic progression (with a fairly constant difference between successive buckets). And while Coach fares go in a roughly geometric progression, the same Coach fare (the one followed by the > symbol) is part of the total fare shown in the chart so the total fares for each sleeper remain in an arithmetic progression.
Thanks very much for the math and "showing your work"! : )

You're welcome. I always like to show the work so others can see how to do it (and maybe point out any errors).

Seems better than just saying "Your $1078 is high bucket."
