Traditionally BF promotions were for Brick and Mortar. Cyber Monday promotions were for online sales.I am extremely disappointed in southwest's lack of BF deals.
Black Friday has lost the original meaning. Companies have been running Black Friday sales for weeks.
On American, not Southwest. Many seats area available for no extra charge, and you are assigned a seat at booking if you don't select one.
Many airlines charge some pax for any seat. Many of those wait until a complimentary seat is assigned at check in.
