Just realized that I am a silver status this year. I’ve never had any type of status in any airline. The website says that I will get complimentary upgrades when available. (I recognize I am only silver so that is unlikely) Do I need to sign up for free upgrades or do I just automatically get selected when available because of my status? Any other benefits with silver status that I may not know how to take advantage of? Thank you in advance.
