I really love the B6 Mint product, but B6 does not provide acceptable irrops support. Even as a Mosaic traveling in Mint, when my connecting flight caused me to miss the last flight of the day out of JFK to SFO, I was given no help, no advice, no food or overnight assistance and no appology. I had stayed up all night since there was no acceptable place to sleep and got myself on the earliest flight out, which I had to book myself since B6 did not offer to help. I wrote them afterwards and they ignored my request for either reward certs or points.
But do I still fly B6? Yes, because I love Mint. I just wish they had some semblence of irrops support for passengers, particularly Mosaic customers.
