Which lens for air shows with E-M1 II

With increased security requirements where camera bags are not allowed at an airshow that I plan on attending, I'm unsure which lens to use. I have both the Panasonic 100-400 and the Olympus 40-150/2.8 with 1.4 TC. Initially I as going with my GX-8 and the 100-400, but now after getting the E-M1 II I wonder if I'm better off with the 40-150 with TC on the E-M1. Any recommendations?

I'd say the 100-400 IF it focuses fast on your oly.  It does on my G7.

Yes there does seem to be the camera bag loophole. I went to the Langley AFB 100th anniversary show and the security blog said no bags, not even a small backpack. Cameras, wear a photographers vest, they said.

So I bought a 25 pocket fishing vest and put everything in there, looking like a clown, and and all these guys with their Canikons walked in saying, "camera bag", even if it was a large back pack. They were still thoroughly searched by the MP's but at least they could bring it in. It took a lot longer to search my 25 vest pockets than it did the camera bags too!

PS, I used a 45-150 Panasonic consumer lens and found it too short for the majority of shots.  I would say take the 100-400 and hope the focus is fast.  The other thing I learned is flightline center is nearly impossible to photograph, say an F-18 just below the speed of sound....or even a Mig 17 in afterburner doing a high speed pass...heck the B-25 was difficult.

very few air shows where the extra reach of the 100-400 won't come in handy at some time.

I would go with the 100-400mm. The 40-150 with the teleconverter provide for only 210mm and you get 4x the overall image size with the 100-400mm at 400mm.

Some options to consider is wearing a jacket with big pockets for a second lens or having a companion carry the second lens. I love the Domke photographer's jacket as I can put a camera, 3-4 lenses, and a flash and not look all that abnormal - unlike using a vest. The British game jackets with their large pockets for shotgun shells are also excellent for this use.
