Data point:

I used just over 32.3k points & ~£150/$197 for a blue econ return fare in Feb from LHR to JFK. These were on cheap dates to fly economy & with only 5 seats selected in the Mint cabin in each direction. Given I'll receive a 10% points rebate on the 32.3k I used due to holding the Jetblue Plus Card, the redemption value I got was 1.55 cents per point (after also including the upgrade fees). Not fantastically good - like my future Trueblue redemptions on Qatar will be - but good enough for my immediate plans.

Needed to move to Mint:

• 2 certs + £104 (~$132) for the outbound ex-UK
• 2 certs alone for the return journey ex-US.

I've been disappointed overall with Jetblue's IT, both on desktop & app. With that said, I ultimately paid VERY little out of pocket for a chance to try out Jetblue's lie-flat Mint product & will attempt to use one of the free Blade helicopter certs on arrival at JFK.

The econ blue cash fare for my flights was $648, while the price for Mint on those flights was $3425. As a Delta Diamond status-matcher, when I factor in the cost for taxes & fees for the award flights & upgrades, combined with the credit card's annual fee ($95), I spent just $424 for a business class return across the Atlantic & have 2 M2M certs remaining. Not bad! That's on top of the other raft of benefits still to use - including those 4x Blade certs.

Can't say I'm likely to continue on with Jetblue after this year & wholly agree with many here that for a nice as this match was, the poor execution of a lot of these perks is reason enough not to commit to B6 long-term. Using Delta GUCs on KL & AF tickets was bad enough, so it's unfortunate that Jetblue have near seemingly matched the user-unfriendliness of those nightmares.

Either way, can't wait to take these flights!
