What Is Add-On in Travel: Definition, Meaning, Examples

Add-on

An add-on (sometimes called an ancillary service) is a supplemental product or service bought in tandem with a primary travel booking like a flight ticket or hotel room. These optional extras enable travelers to customize their journey based on their specific needs, whilst at the same time being an important revenue stream with a high margin for travel suppliers and intermediaries.

The Economics of the Extra

In the modern world of travel economy, the base fare or room rate is often just a start. The business model of many travel companies, and especially Low-Cost Carriers (LCCs) and budget hotels, depends heavily on the “unbundling” of the product.

Unbundling refers to stripping the travel product to the bare minimum (the seat or the bed) to advertise a cheap “lead price.” Every other convenience that used to be included is then sold back to the customer as an add-on. For many suppliers, the profit margin on add-ons (such as travel insurance or priority boarding) is much higher than the margin on the product itself.

Managing Add-Ons in Travel Tech

From a technical perspective, add-on management requires reliable functionality within the CRS (Central Reservation System) and IBE (Internet Booking Engine).

  • Inventory logic: Unlike a room or seat, some add-ons have an inventory constraint (i.e., 10 parking spots available) and some add-ons are unlimited (i.e., WiFi access). The system has to keep track of these counts separately from the regular booking.
  • Dynamic packaging: Today’s booking engines have started to use APIs to aggregate internal add-ons (such as breakfast) and external third-party add-ons (such as a sightseeing tour offered by Viator or TUI) into one transaction.
  • Merchandising: Advanced systems apply logic to the display of appropriate add-ons at the appropriate time. For example, providing a “Romance Package” for a couple booking a weekend stay, but providing “Meeting Room Access” for a business traveler who is booking on his/her own.

Common Types of Travel Add-Ons

Add-ons in travel and tourism can be divided into two categories:

1) Supplier-controlled (internal): Services offered directly by the airline or hotel.

  • Airlines: Checked baggage, seat choice, in-flight food, priority boarding.
  • Hospitality: Early check-in, late check-out, spa treatments, Champagne on arrival.

2) Third-party (external): Services provided by partners that are sold through the booking flow.

  • Travel insurance.
  • Airport transfers/car hires.
  • Destination activity and tickets.

Frequently Asked Questions

What is the difference between an add-on and an upsell?

An upsell is the replacement of the original product by a better version (e.g., upgrade to a suite). An add-on is an additional item bought on top of the original item (e.g., “Add Breakfast to Your Standard Room”).

What is ancillary revenue?

Ancillary revenue is income obtained from the sale of add-ons. For airlines, however, this has turned into an enormous financial pillar, representing billions of dollars per year, separate from selling tickets.

Can add-ons be commissioned?

Yes. When a travel agent or OTA sells an add-on (especially third-party add-ons such as insurance or tours), they will usually receive a commission on that particular item, separate from the commission on the flight or hotel.
