The fares with TAP Portugal are really buggy. I saw a r/t fare that was close to what TAP is publishing on their website and after clicking, I get this error
"The flight you selected is no longer available. Flight inventory changes based on availability and demand and can't be guaranteed until booked.Choose a new flight to continue"
It then update the fare to another $150 higher, then again goes through the same cycle and says new fare is $100 higher. Is this cxloyalty platform quite buggy with many airlines or just TAP Portugal? I don't recall this occurring when it was with Expedia
