Of course they are. Two drivers: The pilot shortage that finally arrived and the fact that overseas carriers have already done it.

Only 2 have to my knowledge
Japan and Canada
If EASA approves it to 67
The FAA will consider it

EASA Has zero plans to revisit the age.

I thought US healthcare sucked?

Only if you have to pay for it.

Most European airlines retire pilots at 55 or 60, since there is very little incentive for them to fly beyond that age. So raising the age doesn't really do much there.

Canada has no age limit. Pilots can fly in country as long as they can hold a medical, however they cannot fly international to a country if they are over the age limit for that country.

Japan has gone to 67. Again, the limiting factor is international, a 66 year old pilot working for a Japanese carrier can't fly to the US, and so forth.

The FAA does not change the age rule, congress does. Congress must change USC 49 in order for the FAA to change the 14 CFR regulation. See 49 U.S. Code § 44729. Age standards for pilots.

Right now most large operators are easily staffing the vacancies. Many senior people have some large sick banks that they will use, effectively retiring them early, yet still having to be paid. And likely paid at the highest rates.
I think the Legacy carriers would like to see the older guys go and replace them with newer and cheaper pilots.

For those of us in our 30s I’m way more concerned with single pilot or no pilot.

There goes career progression. Good luck staying awake on a redeye.
