Sorry, I should have been more clear about what I meant.
If you're not able to choose a Stretch seat at booking you must call. I run into this all the time at work, where our corporate online booking tool recognizes that I'm Summit and lets me book exit row, but not Stretch.
When I book on the F9 site (which I can for personal) I can get Stretch.
When I book on the corporate booking tool (which I must for work) I have to call to be upgraded.
