Related: yield management, dynamic pricing
RM integrates data from reservations, market trends, and competitor actions to d… #
Practical application: a carrier uses RM software to raise fares on a popular route as seats fill, while simultaneously offering lower‑priced “basic economy” seats to capture price‑sensitive leisure travelers. A key challenge is balancing revenue optimization with customer satisfaction and brand perception.
Ancillary Revenue – income generated from non‑ticket sources such as bagg… #
Related: unbundling, ancillary pricing
Airlines unbundle services to create a base fare and sell add‑ons separately, in… #
Example: a low‑cost carrier charges $30 for a checked bag and $15 for priority boarding, boosting total revenue beyond the fare alone. The challenge lies in setting ancillary prices that are perceived as fair while avoiding “price‑scraping” by competitors.
Base Fare – the core price for a seat before any taxes, fees, or ancillar… #
Related: fare construction, fare basis
The base fare reflects the airline’s valuation of the seat based on route profit… #
In practice, a carrier may offer a $120 base fare for a transatlantic flight, adding $50 in taxes and $20 in optional services. Determining the optimal base fare requires sophisticated demand models; mispricing can lead to revenue loss or market share erosion.
Booking Horizon – the time span from the present moment to the farthest f… #
Related: advanced booking window, forecast horizon
A longer horizon provides more data for demand forecasting but also introduces g… #
Airlines often segment the horizon into “early,” “mid,” and “late” periods, applying different fare rules to each. The challenge is maintaining forecast accuracy across all horizon segments, especially during volatile periods such as pandemics.
