Mark, this is what I have done:

Nov 09- injured
About 2 years later when able to be out most of day:
Honolulu to Kauai: Flight about 20 minutes.
Foam earplugs, Bose headphones, Zofran for nausea. Didn't eat before. Headache felt like migrane 10/10 on takeoff and stayed about 2 hours after landing.then went back down to my usual pain normal.

1 year later
Honolulu to Maui: 30 minute flight
Foam earplugs, Bose headphones, Ibuprofen and Zofran. Migrane and pressure headache. Also came during takeoff. Not as nauseated this time, I think due to improvement of PCS.Pain 8/10 but handleable for short time.

Last month: Honolulu to Kona. 50 minute flight.
Wore earplanes. http://www.google.com/search?client=...UTF-8&oe=UTF-8

No pain meds to try out. Pain less of migrane, more behind eyes and forehead.On return flight, pain 10/10 tried sudafed right before.

PLease help thank you. I thought because my PCS has improved so much I would have no problems flying by now.
