The biggest Mosiac benefit is the same-day change (especially now that it can be done 24 hours from the original departure time). By booking the cheapest flight of the day and then switching to the one I actually want I save thousands of dollars a year. I value this more than any of the loyalty perks offered by the legacy carriers.

Between that and getting upgraded to More Space every single time (so far), I also prefer JetBlue over any other carrier's elite program.

For those accumulating Base points to make Mosaic, I received a wake up call when I checked my point total after a Mint trip JFK-LHR.

Total round trip fare: $1,985.05. Taxes and Fees were $1685.05. Base fare was $300.00

Therefore, I will receive 900 base points (3X300) on the total $1,985.05 spend. Not a great outcome.

Hi, I'm close to getting Mosiac and wanted to clarify this point you made. So basically i can book the lowest fare available and within 24 hours, decide to switch the flight to another available one with no fee or extra cost? So if I book the cheap red eye layover which is $1000 less lets say, I can switch to the non stop originally more expensive flight within 24 hours with no cost different? That seems like a really good perk if that's the case, right? I'd probably always book the cheapest one and switch if it's not a popular route!

You may want to write in about this — other airlines grant miles on carrier-imposed surcharges (looks like YR for JetBlue, YQ elsewhere). I don't think JetBlue has ever charged them before, so this may be an IT error.

I just voted with my wallet. Just did round trip JFK/LHR via BA for $2000. BA allowed me into JFK Concorde room at T7 and the LHR T5 First Wing is now also open. I usually don't care about the lounges, but pricing was same and schedule was better for me. The BA 777's were less than half full.

Yes, I thought about the fastrack to status ($15k credit card spend) but reached the same conclusion. Status on other airlines gets me into More Room seating at time of booking, and possibly upgrades to F. Mosaic gets me ... opportunity for a More Room seat at T-24 but I generally find that all the aisle seats are taken long before that (sometimes several weeks out). So useless for better seats. The other soft perks are also fairly worthless as I rarely check bags and have Clear/Pre-Check. Early Boarding is about the only consistent perk that has value.

"Award winning program" - what award? LOL

Agreed. I've been Mosaic for 7 years. Thought about the $15k fast track and decided to skip it. Have been happy with Delta Platinum even though Jetblue has more directs for me. And if I do decide to fly Jetblue, I still have their CC for the free checked bag.

The problem with airline status for CC spend is that it locks all those points into airline miles, which seem to be depreciating faster than just about anything else. Not unique to JetBlue, of course.

That isn't correct. What OP meant was 24 hours of flight departure.

I'll give you an example- BOS-JFK 8pm flight costs $50 and BOS-JFK 9am flight costs $80 on a particular day. As a mosaic, you can book the cheaper BOS-JFK 8pm flight. Before 24 hours when your ticketed BOS-JFK 8pm is scheduled to depart, you can call the Mosaic desk to make a free "same day change" to the earlier (and more expensive) BOS-JFK 9am flight thus saving you $30.

The only consideration to keep in mind is that Jetblue does not oversell flights and if the BOS-JFK 1pm flight is already sold out 24 hours before your ticketed flight is scheduled to fly, this benefit is no good to you. This wouldn't have been an issue in the past but as someone that takes advantage of the free 24 hour before departure free same day flight change, I recently almost lost the ability to change to my desired flights due to lower frequency, higher load factors post-COVID flight scheduling (which would have been disastrous as I was using Jetblue to position for international business redemption flights on a different ticket).

The general consensus left and right is the Mosaic status isn't really beneficial period compared to most other program elite status. Even the supposed Mosaic benefit of free EMS seats at airport checkin creates unnecessary burden since the alternative of allowing Mosaics to select EMS seats free during online checkin 24 hours before flight already prevents the loss of upsell of EMS seats to non-mosaic customers. Jetblue can easily crunch the numbers on how much EMS seat upgrades they sell within 24 hours of flight departure.

Pat on your own back award :D

Which is now also devalued, as Aadvantage lowest tier now gets to board with Mosaics.

I'm also interested in this now. Could you do *all* of this at T-24? Book the cheaper flight and immediately do the same-day confirmed to the more expensive one? Also, does this work for Mint?

If "by all" you mean booking the cheaper outbound flight you want to travel within 24 hours of departure, then yes. But it's my experience that Jetblue flights are most often much cheaper booking 1-2 months in advance than buying 24 hours before departure. I have never purchased Mint but I'm sure the 24 hour "same day" complimentary change should work for Mint seats as well. You can always call and confirm with any Jetblue phone agent to be 100% certain

Understood, but I've certainly been in a position where I'm booking the day of and one flight is 3x more expensive than another, and with this, I won't have to worry about that at all. I hadn't realized that this Mosaic benefit was a real benefit until now.

Thanks for this advice. I received extra base miles this week for this trip. Much appreciated, B6.

Update: I received a bonus of base points this past week for this flight. Very surprised/pleased.
