Just finished SAN-IAH-SAN with family of FF. On both flights, only 1 (middle on bulkhead) of 3 would take my card. So, I hooked up my 1-to-2 headphone splitters and let the kids watch TV. Great for me as only paid for one TV, but a problem CO should have fixed a week ago on the outbound and didn't bother to fix even on today's inbound on the same equipment.
