Good until midnight CT tonight - DollarFlightClub.com offers Premium (reg. $69) or Premium+ (reg. $99) membership for $1 for the first year. Cancel anytime.
This site sends you notices when special deals occur on flights, such as mistake fares. The reviews I've read haven't been great, but at $1/year I figure it's worth a shot for when we can actually travel again.
IMPORTANT: The landing page doesn't talk about Premium+, but when you go to purchase you can select it as an option. Web site says Premium+ has all that Premium has and more, and they are the same price ($1/first year).
I signed up with a Citibank Virtual Credit Card.
