The industry practice is that flight crew generally get a pass on oversized carry-ons...because their luggage is usually designed to fit in a bin. It might be long, but width/depth will be good.
I have never had TSA or anyone else hassle me about a 26" high bag. Even when traveling on a paid ticket, I use my crew badge as ID for that reason (in case they don't notice all the crew tags).
