What is the Difference Between Qantas and British Airways?

Qantas and British Airways are both founding members of the oneworld alliance and offer services between Australia and Europe, with their home bases and major hubs at Sydney Airport and London's Heathrow Airport, respectively. Some key differences between the two airlines include:

Network: Qantas flies direct between London (Heathrow) from Perth, or via Singapore with flights between Sydney, Melbourne, Brisbane, or Perth. British Airways, on the other hand, connects more than 200 destinations in 80 countries throughout Europe, North America, South America, Asia, Africa, and Australia.
Services: Qantas offers seat selection (paid or complimentary) and online check-in via qantas.com, while British Airways does not provide these services for Qantas passengers. However, Qantas passengers can benefit from a codeshare service between London and various destinations in the United Kingdom and Europe when flying with British Airways.
Frequent Flyer Benefits: Qantas Platinum and Gold Frequent Flyers receive certain benefits when traveling with British Airways, such as lounge access, priority check-in, and additional baggage allowance.
Cabin Classes: Both airlines offer different cabin classes, including First, Business, Premium Economy, and Economy. The quality and services provided in each class can vary, with some travelers preferring one airline over the other based on their personal experiences.

Ultimately, the choice between flying with Qantas or British Airways depends on factors such as route, fare, and personal preferences.
