How To Increase Your Chance Of Getting An Upgrade To First Class

What factors can increase my chance of getting an upgrade to first class?

If you're trying to get a free upgrade to first class, first of all, look the part. Dress up, look your best, show up early, be polite and courteous. Be really nice to the people at the boarding gate. See if coach is sold out and if there are any available spots in first class, and then see what they can do for you. Sometimes they might let you go, other times they might ask you to give some of your frequent flier points, or pay a nominal fee for the upgrade to first class.
