JetBlue really impressed us last week.

My wife and I were on an Economy revenue one way ticket SFO to JFK on Dec. 23. My wife is Mosaic whereas I hold no status.

When checking in (we had checkin luggage so went upto the counter), the agent recognized that the flight was full and was perplexed why my wife hadn't been assigned a seat but I had. We really wanted to sit together. We enquired for and then declined the cash Mint upgrade offer, noting that we could fly Economy roundtrip to Europe for that cost of $650 pp.

To this, the agent checked us in, gave us our boarding passes and advised us to head to the gate, and that "she will see what can be done about our seats." We thought this meant she would find a way to assign us Economy seats together.

Well, she upgraded both of us to Mint for free! I've flown Mint before and my wife and I really enjoyed our flight!

Kudos to the JetBlue staff and their generosity. Definitely a unicorn event. Would love to hear similar stories from the FT community!
