Provides Aer Lingus's published ancillary fee data — checked and cabin bags, seat selection, priority boarding, check-in, changes and payment fees — with price ranges, when each fee applies (at booking, later, or at the airport), source URL and the date checked, usable for computing a true trip cost.
Enables AI assistants to calculate the true cost of flights by adding airline baggage, seat, priority boarding, check-in, and payment fees to fares, using sourced and dated fee data across many airlines.
