Global Alliance Intelligence

Star Alliance vs. oneworld vs. SkyTeam

Lounge Access Rules & Domestic Exceptions

⚠️
The US Domestic Exception Rule:

United (Star Alliance), American & Alaska (oneworld), and Delta (SkyTeam) restrict lounge access for their own domestic elite members when traveling purely on domestic itineraries within the 50 US states. However, foreign alliance elite members (e.g., a Lufthansa Gold or British Airways Silver flyer) traveling on pure US domestic economy flights are entitled to United Club or Admirals Club access!

Frequently Asked Questions

Can I earn miles on an airline I don't have an account with?

Yes. When booking or checking in for a flight on any alliance partner, enter your preferred frequent flyer number from any other carrier in the same alliance (e.g. enter your United MileagePlus number when flying Lufthansa or Singapore Airlines) to earn miles in your primary account.

What is the difference between an alliance and a codeshare?

An alliance is a multilateral network of airlines offering reciprocal status, baggage, and lounge privileges. A codeshare is a specific bilateral commercial agreement between two airlines where one places its flight code on the other's aircraft, which can occur between alliance partners or non-alliance airlines.

Which alliance is best for round-the-world tickets?

Star Alliance offers the widest global coverage with 1,200+ destinations via its Book & Fly tool. oneworld offers the “oneworld Explorer” pass which is uniquely priced by continent visited rather than total miles flown, making it the most cost-effective for deep multi-city exploration.
