LAX to CDG

If it's the same airline and all on one ticket you should be fine. Should something happen and you miss the flight, then the airline is responsible for getting you on the next available flight at no change.

Changing planes in Boston should mean nothing more than a gate change.

Questions: where are you seated on the flight to Boston? If well towards the front of the plane, that will expedite your exit. If not, that could slow you down.
Another question: are you checking a bag? Since you are on one ticket you will be able to send it to through to Paris from LAX, but, is Paris your final destination?
That will also help- make sure your Paris lodging is on it. I would also take a photo. (You don't say if you are continuing on from Paris from CDG.)
In both cases (if you are using carryon) I now take a packing cube with a change of clothes, etc in my personal item in case there's a glitch.
Good luck and safe travels!

Is this on a Delta/SkyTeam [Air France] ticket? It looks like Delta is now using the international Terminal E for all international flights, and Terminal A for the majority of domestic flights. There is supposedly an airside bus that will take you from Terminal A to Terminal E for your outward journey. However, if you are on the same itinerary on the return, after exiting immigration control and re-checking your bags in Terminal E, you will have to make your way to Terminal A and go through security again to catch your domestic flight - I had to do this after arriving from Rome back in 2024. Hopefully the flight from LAX will be early or on time.

Guessing it’s JetBlue?

I do think the airlines make a difference. If this is on Delta or Air France one of those area carriers, I would pick the longer connection because you will have to change terminals.

Using the same airline for all the legs of the flight

But is it all one ticket?

I am puzzled an airline has two flights from Boston to Paris departing 22 minutes apart
( Or is it the LA to Boston leg that has 2 flights just 22 minutes apart?)

Thank you for the responses. It was Jet Blue, so the second leg of the flight should wait for the first to arrive and board the second flight. I was uncomfortable with such a short time layover. I did try to set up a flight on JB to Boston, but then fly to Paris on Air France, thinking it would help us be a bit more rested than flying over in a 737. That proved to be too costly. We will most likely just go with Air France.

This generally is not true. Airlines rarely hold a flight because other flights are late. If your first flight is too late for you to make a connection, they will rebook you rather than wait for you. This is assuming the flights are all on one ticket.

If I understand your original plan, you wanted to fly Jet Blue to Boston and then Air France to Paris. In that case, the connection times would definitely NOT be enough. Jet Blue and Air France are not parter airlines, so you would need to collect any checked bags, recheck them and go through security again, possibly changing terminals. Keep in mind that international flights often begin boarding as much as an hour ahead of the scheduled departure time.

I once flew to Europe through Boston on Delta/Air France and had to make the transfer between Terminal A and E. There was a shuttle bus, but it was a very slow transfer - waiting for the bus, driving a circuitous route, walking the length of the second terminal. I would want 1-1/2 to two hours between flights if needing to do this.

Just so there’s no confusion, JetBlue flies to Paris, so the original itinerary was points driven somehow, all on JetBlue.

OP seems to have abandoned that idea and Boston in general, and is now looking at nonstops from LAX.

Reading between the lines….

I flew nonstop from LAX to Paris on Air Tahiti Nui. I was pleased with flight and service. They are part of One World Alliance so rerouting options are available in case of irregular operations.
