Hi, despite traveling for most of my career and 90% on AC. I think this is actually the first time I have one of these things. On a recent flight from YYC to YYZ, my seatback screen wasn't working (I usually don't care as I have my iPad or work) and a FA immediately came over during boarding to offer me a free WIFI voucher as she knew it wasn't functional. I declined as I have WIFI as a benefit, she said she'd come back with a compensation request form then vanished before I could wave it off.

Anyhow, I filled it in and she gave me the receipt portion. It has the flight number, date, and form number. What the heck do I do with this thing?
