Hurry: 90% Off Promo Code For Frontier Airlines Flights, Today Only

Frontier may be the worst airline in America that operates under its own brand. An ultra low cost carrier in the model of Spirit, they’re all about low prices and charging ancillary fees.

In fact they kicked an unaccompanied minor off a flight when they screwed up and failed to collect a fee. Two passengers were recently kicked off a Frontier flight after complaining to each other about an 8 hour delay. The airline even apparently kicked a blind man off a flight because he was blind.

So I wouldn’t normally choose to fly Frontier, all things equal. But what about when they’re ‘selling’ flights for almost free?

Frontier is running a 90% off sale with promo code SAVE90 valid for bookings made today only.

Travel on one-way or roundtrip domestic flights August 28 through October 4 on Mondays, Tuesdays, Wednesdays, Thursdays and Saturdays only (no Fridays or Sundays) and September 4 and 5 are blacked out.

I pulled up a sample roundtrip from Austin to Las Vegas. With this sale they will sell me a roundtrip for $50, remember that only the fare and not taxes are discounted.

I’m not sure their calculations here make any sense, they claim an airfare of $168, taxes of $48.52. Every calculation I’ve tried doesn’t give me their total but it’s still a good price.

On the other hand here’s what the flights would cost booked outside of Frontier without the discount.

90% off of this fare, plus taxes, would yield $33.20. Go figure.

Several markets are excluded from the discount:

  1. Frontier sells its fares deceptively, which is why the math doesn’t work. I think they have a “base fare”, which they give you the discount off, but also charge a “fee” where the discount isn’t applicable. I guess they have a lawyer who thinks this is legal; beats me.

    There are obviously some very cheap airfares here and, if you you can make it work (not necessarily easy), it’s probably worth booking. I’ve flown Frontier a few times and it’s been OK — for the price. You obviously have to deal with their luggage restrictions (no full size carry on) to make it worthwhile. They’ve now signed up with TSA Precheck, which makes the experience better.
