I've had the same question. I always thought that maybe they just make a low pass at the airport and detach the banner first with some device, then go around again and land. I also always thought that the banner planes must use podunk airstrips which would allow this. Just my pure idle speculation.

I love it at the beach with a strong headwind, the piper cubs towing are barely making headway!
