question: What type air travel package can be purchased at a discounted price bythird largest global airline alliance? 
answer: round-the-world ticket
context: Title: Opaque travel inventory
  Passage: An opaque inventory is the market of selling unsold travel inventory at a discounted price.  The inventory is called "opaque" because the specific suppliers (i.e. hotel, airline, etc.) remain hidden until after the purchase has been completed.  This is done to prevent sales of unsold inventory from cannibalizing full-price retail sales.  According to TravelClick, the opaque channel accounted for 6% of all hotel reservations for major brands in 2012, up 2% from 2010.
  Title: Round-the-world ticket
  Passage: A round-the-world ticket (also known as round-the-world fare or RTW ticket in short) is a product that enables travellers to fly around the world for a relatively low price.  RTW tickets have existed for some time and in the past were generally offered through marketing agreements between airlines on several continents.  Now, they are almost universally offered by airline alliances such as SkyTeam, Star Alliance and Oneworld, or else by specialist travel agencies that will spend time helping customize a trip to the consumer's needs.  Prices vary but are generally in the range of 3000–5000 USD for an economy-class ticket.  Sometimes, depending on airline and stops, it can be as low as 1171 GBP (~ 1829.57 USD).  An alternative for a round-the-world ticket is a continent pass.
  Title: Oneworld
  Passage: Oneworld (marketed as oneworld; CRS: *O) is an airline alliance founded on 1 February 1999.  The alliance's stated objective is to be the first-choice airline alliance for the world's frequent international travelers.
