Perhaps this article should be temporarily withdrawn and reviewed for accuracy?
As it stands there are multiple errors including confusion between the OW connecting rules and stand-alone lounge access rules.
For example the statement that lounge access is not permitted on domestic sectors in the US is incorrect. If you are arriving long haul OW J/F and connecting to domestic, you will be welcomed into the lounge even if your onward flight is economy. You’ll also get access for Nth American and Caribbean flights.
(While not relevant, the discussion about ineligible access in the US is not complete. For example, there are qualifying flagship domestic AA flights from MIA to LAX, and several mainland cities to Hawaii. Domestic class of service access is not limited to JFK-LAX/SFO.)
Other purported exclusions are more nuanced. If you arrive BA F into London, you’ll have Concorde Room access before your onward flight to Europe. Same with Qatar with their Al Safwa lounge. These lounges may fall outside OW rules, but the rule is still applied in certain circumstances
Perhaps the second part of the article could focus on lounge access by airline… because there are some great additions to the stated OW policy. For example arriving BA F Gets Concorde Room. And Cathay grants lounge access based on the highest class of service that day, regardless of flight length. If you have a business class ticket TPE-HKG followed by economy to New York, you’ll get business class lounge access in TPE and HKG (before your long haul economy flight).
