# What is Ancillary revenue?

Ancillary revenue is income from services stripped out of the ticket price and sold separately, such as bags, seats or changes.

Also called: Unbundling, Ancillaries.

## How it works #

Unbundling lowers the advertised base price and moves the margin into components that appear later in the booking path. For price comparison that means only the total including the bag and seat actually needed is comparable. At network airlines unbundling keeps spreading into fares that used to include everything.

## Not to be confused with #

Ancillary revenue is not the same as hidden fees: the services are itemised and optional, but comparing them against all-inclusive prices becomes harder.

## In German #

The German term is Zusatzerlöse. [German version of this term](/de/glossar/zusatzerloese)
