For example, I looked for a plane ticket from my home base in Denver to Miami for a beach vacation in January. With this promo, I can fly round-trip for just $217, compared to $237 without the promo code.

This is not a huge Savings – but for me and three of my friends on a girls trip, it would add up to $80 for four people.

“10% discount applies to round-trip flights,” according to a United representative. However, when I searched for sample flights, I was constantly receiving an error code when I tried to search one-way, so your one-way options may be more limited.

Bottom line

Is United’s Halloween Flash Sale a scary good deal? Hey, in today’s economy, a 10% discount is nothing to sneeze at. It’s too bad you can’t use it for it Holiday travel during Thanksgiving and New Year’s (see blackout dates above), but you can use it for other trips between now and March 9, 2026.
