Prices are one-way per traveler: the program's points or miles plus taxes and carrier fees in USD, as AwardTool observed them in the observation window. Award space changes constantly. A seat we saw may be gone, and space we haven't seen may exist. Always confirm with a live search before transferring points; most transfers can't be reversed.

Business class compared with economy, by program

Each program's lowest one-way business-class and economy awards on IAD→ONT, in its own points or miles, and how many times the economy points the business-class award needed. — in the last column means one of the two is a mixed-cabin award or was not seen on 2 or more dates.

Each program's lowest one-way business-class award by departure month, in its own points or miles, with the taxes of that month's lowest award and the program's open dates that month under it. A price without taxes had none reported for that month. — means the program showed no business-class space that month.

Lowest prices among the dates we observed, by departure month. A record, not a forecast.
