15 Miles per Dollar Through February 19 At United Portal

United MileagePlus Shopping is offering big shopping portal bonuses at specific retailers through February 19, 2018 at 11:59 PM ET.

Big Holiday Shopping Portal Bonuses

United, American, and Southwest are all offering bonuses for shopping through their portals. The bonuses are in addition to what you’d already be earning by shopping through the portal. Shopping portals allow you to earn miles by making your normal online purchases through your favorite online stores. Just by starting at the loyalty program’s portal and using its link to your favorite online retailer, you can get extra miles for your purchases.

With each holiday shopping promotion, the more you spend, the higher your return is.

15 Miles per Dollar Today Only at United Portal

The United shopping portal is offering 15 miles per dollar today only (until 11:59 PM ET on 1/22/17) at a number of stores that normally offer only 2-5 miles per dollar.

I value United miles at 1.6 cents each, so getting 15 miles per dollar on your purchase is like getting 24% of your purchase rebated back in United miles (in addition to the 1x or more you're getting on your credit card purchase normally.)

Here are the 15x stores:

TODAY ONLY: Get 51 Miles Per Dollar on Magazine Purchases

The American Airlines eShopping portal is offering 50 miles per dollar spent at magazines.com through today (May 27, 2016.)

Portals are a way to earn extra miles. You start your online shopping at a portal, click a link that adds cookies to your browser to prove you started in the portal, and then purchase things on other sites at normal price while getting bonus miles.

Portals generally offer small miles per dollar at stores that have small margins. For instance, you can get 1 bonus mile per dollar at walmart.com through the American Airlines portal.

Huge Hat Tip to reader Daniel for emailing me about this deal. Email me your tips!

Today the AAdvantage eShopping portal tripled the earning rate on magazines.com to 60 American Airlines miles per dollar through November 30, 2013.

Stacked with the ongoing promotion that is awarding up to 2,500 miles for $250 in purchases through the portal (and fewer bonus miles for smaller purchases), you can buy up to 17,500 American Airlines miles for 1.43 cents each until the magazines.com promotion ends. And you even get some magazines thrown in for free.

Spend $250 or more and get 2,500 miles

All spending from all stores in the portal before December 2, 2013 will be added up to determine your bonus amount.

If you can spend just over $75, $150, or $250, you will earn at least 12x miles per dollar on every purchase because you'd get 10x through this

Basically Free $35 Worth of Shopping at AAdvantage eShopping Mall

American Airlines' AAdvantage eShopping mall just sent me the following:

If I spend $35 of more, I get 2,000 bonus AAdvantage miles on top of the normal mileage earning from the mall. Since I value 2,000 bonus AAdvantage miles at $35.40, it's like being rebated my $35 worth of shopping in miles.

Forum Buzz: Why You Shouldn’t Participate in the 250 Taca Miles Portal Deal

According to this very active thread on FlyerTalk, Taca Airlines is offering 250 LifeMiles for each purchase made through its e-shopping portal through October 31st. (Hat Tip Mommy Points.) The most important part of this deal is, according to the terms and conditions, there are NO minimums on purchases. Conceivably, you could order many inexpensive items separately and rack up Taca miles quickly.

Many in the FlyerTalk forum are attempting to order multiple $1 items from various stores in the shopping portal. If everything goes as planned, they will receive 250 miles for each $1 purchase.
