I feel like they are changing the tiers around hourly, or people are not reading this right. The way the webpage is structured, it is quite convoluted. I had to read through it a couple of times, and make sure to select the 'mosaic' section near the top, otherwise you are reading pick-your-perk for non-mosaics who have earned these silly tiles.

Mosaic 1 compared to Mosaic in 2020/2021 - All the benefits are at at least as good as Mosaic was before 2022. I think in 2021, you could select EMS seats at booking for a fairly high points fee or at the gate. In 2019, I remember paying around 800 points for EMS on transcon flights, ~400points for 3-4hr flights. Then, they bumped up the pricetag to 2k/3k for similar flights. The only other way to get EMS was free at the gate if the agent would allow it (no specific policy for that). Then in 2022, they came out with the max price of 200points, and 200points refunded after flying, and free EMS at check-in. There is no mention of points to pay for EMS ahead of time going forward in 2023, but EMS at check-in is better than it was pre-COVID. Other than that, everything is the same, except you cannot qualify for mosaic with 12kpoints/30 segments.

BTW, I booked a points ticket yesterday (as Mosaic) for travel in March, and selected EMS at no charge. It showed $0/0points for all three people in my group. Likely this is just the crappy IT system.

This could have been a lot worse. I am still waiting for the major point devaluation or other changes to settle out, like the fact that you can't book points bookings anymore with travelbank.
