My one experience with Silver was not great. We used Silver on AA codeshare in June 2022. Our flight into EIS (from SJU) was fine. But they cancelled our return flight the day before our trip with no alternatives. We ended up booking a last minute water taxi to STT where 4 of us travel back on one itinerary and 7 on another. Silver blamed AA and AA blamed Silver - no one took accountability or reimbursed us the water taxi charge. It was a frustrating experience where we were stranded in the BVI's with a flight out of SJU - but no way to get there.

Happy to hear that others had better experiences.
