What It Is
A mandatory daily fee charged by hotels for amenities such as pool access, fitness center use, Wi-Fi, and newspaper delivery. Resort fees are often not included in the advertised room rate and can add $100+ to a typical stay.
Why Companies Charge It
Resort fees allow hotels to advertise a lower room rate while collecting additional revenue. Online travel agencies may not display the total price including resort fees until late in the booking process.
When It Is Legitimate
When the fee is clearly disclosed in the total price before booking and covers amenities the guest will actually use.
When It May Be Excessive
When resort fees exceed $50/night for basic amenities; when fees cover services that should be included in the room rate; when the total cost including fees is not displayed upfront.
Warning Signs
Advertised prices that seem significantly lower than comparable hotels; fees labeled "resort fee," "destination fee," or "amenity fee" added at checkout.
Consumer Questions to Ask
"Does this hotel charge a resort fee?" "What is the total price including all fees?" "Can the resort fee be waived?"
Documents Where It Appears
Hotel booking confirmations, bills at checkout, online booking pages.
How AI Analysis Can Help
AI can scan booking confirmations and hotel bills to identify resort fees, calculate the fee as a percentage of the base room rate, and compare fee amounts across properties.
🧳 2. Baggage Fee (Carry-On / Checked)
What It Is
A fee charged for checking luggage or bringing carry-on bags on an airline. Basic economy fares often exclude even carry-on bags from the ticket price.
Why Companies Charge It
Airlines unbundled baggage from ticket prices in the 2000s to offer lower base fares while generating billions in ancillary revenue from bag fees.
When It Is Legitimate
When the baggage fee is clearly disclosed at the time of booking and the passenger has the option to choose a fare that includes bags.
When It May Be Excessive
When bag fees exceed $40 each way for standard checked bags; when carry-on bags are excluded from basic economy without clear disclosure; when fees increase at the airport compared to online.
Warning Signs
Basic economy fares that don't include carry-on bags; baggage fee amounts that differ between booking and airport check-in.
Consumer Questions to Ask
"Does this fare include a carry-on bag?" "What is the checked bag fee?" "Is it cheaper to prepay for bags online?"
Documents Where It Appears
Airline booking confirmations, ticket receipts, baggage fee schedules.
How AI Analysis Can Help
AI can scan booking confirmations and airline fee schedules to identify baggage costs, compare total cost of different fare classes, and recommend the most cost-effective option.
🪑 3. Seat Selection Fee
What It Is
A fee charged for choosing a specific seat on a flight. Standard seats, aisle seats, window seats, exit rows, and premium seats all carry different fees, with some airlines charging even for random seat assignment.
Why Companies Charge It
Seat selection fees generate significant revenue for airlines by monetizing what was once a free service.
When It Is Legitimate
When seat selection is optional and clearly priced before booking confirmation.
When It May Be Excessive
When seat selection fees exceed $50 for standard seats; when families are required to pay to sit together; when random seat assignment places party members apart.
Warning Signs
Seat selection fees that appear only after entering payment information.
Consumer Questions to Ask
"Can I choose seats for free?" "Will my family be seated together without paying?"
Documents Where It Appears
Booking confirmations, seat selection screens, airline fee schedules.
How AI Analysis Can Help
AI can analyze booking documents to identify seat selection fees and compare total costs across airlines for the same route and seat preferences.
