I live in Denver and I have a BA companion voucher expiring in April. I was hoping to try use 150k points to hop over to London for a week with my mom, but I can't seem to find any award availability online. When I search for First, it shows plenty of availability, but when I click through it says "Your requested class is not available. The highest available class has been displayed." and displays Club World... I'm just wondering if First class award space just isn't available on this route or if this is a problem I could solve with a call to BA. Any ideas?
