Frontier Airlines is out with a promotion whereby you can earn an additional 5,000 miles for each qualifying round trip you book and fly between May 6, 2026, and August 31st, 2026, provided that you register for the promotion at least 24 hours prior to departure of your flight. You can earn up to 20,000 bonus Frontier miles this way, which is a nice little bonus if you’re flying Frontier. Note that you must register by May 31st, so it’s worth registering now even if you don’t anticipate using the promotion.

Quick Thoughts
Keep in mind that you need to register for this promotion at least 24 hours prior to departure of a qualifying flight, and you must register by May 31st, 2026 in order to take advantage of this offer. I would therefore recommend registering even if you don’t intend to use the promotion. Frontier does not serve my home airport, and I don’t anticipate flying Frontier between now and the end of August, but I’ll register anyway just in case I end up in a situation where I need to book an unexpected Frontier flight. I would rather position myself to earn the extra 5,000 miles than leave them on the table if something comes up.
