Back in July we watched the 60k sign up bonus offers on each of Citi's AAdvantage Platinum Select MasterCards (the personal and business) disappear.

The weekend is over. Blah. But we're giving away a $51 Southwest gift card to brighten your Monday.

Longtime and generous reader Caveman, who I'm going to be referring to as CaveDweller from now on per his request, is offering one lucky reader a $51 Southwest gift card. Southwest gift cards are fully transferable and don’t expire. There are two ways to enter:

GIVING AWAY A $51 GIFT CARD ON SOUTHWEST AIRLINES. FOLLOW AND RT TO WIN.

Alaska Airlines bought Virgin America last year. In January, we saw the two companies merge and Virgin America award space started showing up on alaskaair.com.

Each loyalty program, Alaska Mileage Plan and Virgin America Elevate, has their own co-branded credit card issued by separate banks.

After enough data points and confirmation from a reliable source, Doctor of Credit has outlined a new rule to follow when applying for Bank of America credit cards.

You can now see Singapore Airlines award space on united.com, which means you can book Singapore award space on united.com. This was not the case as of a few days ago.

Singapore doesn't really release premium cabin award space to its Star Alliance partners, so you won't see much Singapore Business and First Class on United's website.

I heard about Kiwi.com from a friend, dry on the miles front, who was traveling in Europe this past summer and wanted to find the cheapest cash option to get him back home to the United States. Kiwi.com is an online travel agency with a fare aggregator and metasearch engine that used to go by Skypicker.com until the company re-branded under the name Kiwi in 2016. And lots of people are talking about it.

But there are tons of aggregators and metasearch engines for travel these days.

A few days ago I wrote about the award chart Singapore Krisflyer just published for flying their newest partner Alaska Airlines.

I noted that within Singapore's list of conditions for the chart is a confusing line prohibiting "transfers"...

...which leads one to believe that awards will price per segment. It’s not totally clear, however, that a transfer and a connection (i.e. layover) are the same thing--most people don't call layovers or connections transfers. There are prices on the award chart that seem just a little too cheap if "transfers" (layovers) were indeed permitted, though.

Singapore Airlines has published an award chart for flying their newest partner Alaska Airlines, and there are a lot of excitingly low prices. This is especially exciting as Singapore miles are one of the easiest to collect.

Do you have a debit or credit card issued by Citi?

More specifically, do you have a personal credit or debit card (not business), excluding the Costco and Chairman credit cards? If the answer is yes then you're eligible for Amazon and Citi's latest promotion: a four month free trial of Amazon's premium music streaming service, Amazon Music Unlimited.

New users can get a free month trial any time. Citi and Amazon's new deal is for a three month trial, but you can stack the two promotions for a total of four months.
