I am finding cheap LH Economy flights via Google Flights. When I get redirected from GF to LH, I can book them, but they book into Economy Light.
I'd rather book them as Economy Basic, since I want to credit them to UA MP and Economy Light would only credit 50% PQM instead of 100% PQM.
When I try to book the exact same flight through the LH website, rates are at least double, as it's only showing me the Basic Plus fares. Basic Light and Basic are hidden.
Is there a way to "upgrade" to standard Basic with a flight in the shopping cart? I'm not seeing it.
