SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Budget airlines advertise headline fares that exclude baggage, seat selection, check-in, and ground transfer costs, making real price comparison nearly impossible. This Skill totals the hidden fees and remote-airport transfer costs so you can compare the actual number against the advertised fare. ## Core Features & Use Cases - Fee Research: Looks up current baggage, seat, and check-in fees charged by carriers like Ryanair, Wizz Air, and easyJet. - Transfer Costing: Prices the ground journey from secondary airports (e.g., Beauvais to Paris, Hahn to Frankfurt) including time and fare. - Verdict Output: Ends with one real number against the headline fare and a clear verdict, not a raw fee table. - Use Case: You find a 19 euro Ryanair fare to "Paris" and want to know what it really costs with a cabin bag and the 80-minute Beauvais bus before booking. ## Quick Start Ask the assistant to work out the real cost of a Ryanair flight to Paris Beauvais including the cabin bag fee and the airport bus.

Frequently Asked Questions about budget-airline-math

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I find the real cost of a Ryanair flight?▼

Add the cabin bag fee, seat selection, and airport transfer cost to the headline fare before comparing. This Skill searches current Ryanair fee pages and prices the ground leg, such as the roughly 80-minute Beauvais bus to Paris at 12 to 18 euros each way.

What hidden fees do budget airlines charge?▼

Budget airlines charge for cabin bags, seat selection, airport check-in (55 euros on Ryanair), gate penalties up to 75 euros for oversized bags, and boarding pass reissues around 20 euros. The Skill totals these against the advertised fare.

Does this skill book flights or check in for me?▼

No. The skill is strictly read-only: it never signs in to airline or agent accounts and never books, holds, checks in for, or buys anything. It only researches public fee and transfer information and returns a cost comparison.

What happens if an airline fee page will not load?▼

If a fee page fails to load, the skill uses the last published figure and marks it as indicative. If an airport transfer has no public timetable, it reports the journey time and notes that the fare needs checking locally.

Why do budget airlines use airports far from the city?▼

Secondary airports like Beauvais (sold as Paris, about 80 minutes away) and Hahn (nearly two hours from Frankfurt) have lower landing fees, enabling cheaper fares. The skill prices this transfer as part of the ticket so the comparison reflects the real journey.
