How are seat upgrades, baggage fees, and other add-ons categorized?

Short answer

Airlines categorize seat upgrades, baggage fees, and other add-ons as ancillary services, which are charges separate from the base ticket price. These add-ons usually post as separate transactions on card statements and may appear days after the original ticket purchase.

Common ancillary categories

  • Baggage fees: Checked bags, carry-on bags on some carriers, overweight or oversized baggage
  • Seat selection and upgrades: Preferred seats, extra-legroom seats, and cabin upgrades
  • Boarding priority: Early boarding and priority check-in
  • In-flight services: Meals, beverages, Wi-Fi, and entertainment
  • Travel services: Pet transport, unaccompanied minor fees, and travel insurance

How ancillary charges appear on transactions

Ancillary services are processed separately from the ticket purchase:

  • Charges often post as individual transactions
  • Posting may occur days after the base fare settles
  • Each add-on may require its own receipt
  • Transactions may not reference the original ticket number

This separation is normal and does not indicate duplicate or failed charges.

Key implications for business travel

  • Seat upgrades, baggage fees, and other add-ons post as separate airline transactions
  • Charges may appear days after the base airfare settles
  • Each add-on may require its own receipt and categorization
  • Finance teams should expect multiple airline charges tied to a single trip

Ramp helps by automatically collecting receipts, grouping related travel charges, and maintaining visibility across all trip-related transactions, making it easier to review and categorize ancillary spend without manual reconciliation.
