Credit card sign up bonuses, spending on credit cards/through portals, and earning via flying are the major opportunities to earn big chunks of rewards. But being a true miles and points enthusiast means taking advantage of even the little opportunities when you can, that only take a minute or two to sign up for and over time add up to big savings. Every penny--or mile--counts.

Here are two ways you can easily boost your balances this weeks.

Not long ago you saw us report on the prevalence of Etihad First Class Apartment award space available between Abu Dhabi and New York City.

It's really easy right now to earn a lot of American Airlines miles fast.

American Airlines has released a batch of Business Class award space to London (some totally lie-flat seats, some angled lie-flat) from many cities, January 2018 through the end of the calendar (April). This is news because American Airlines doesn’t normally have so much premium cabin award space, and the majority of the other award space bookable with American Airlines miles to Europe is on British Airways which incurs ridiculously expensive fuel surcharges.

I would act quickly if you want to book this award space, as much of it has already been snatched up.

The Citi / AAdvantage Platinum Select MasterCard is now offering 60,000 bonus American Airlines miles after spending $3,000 in the first 3 months.

The CitiBusiness / AAdvantage Platinum Select World MasterCard is also offering 60,000 bonus American Airlines miles after spending $3,000 on the card in the first three months.

The normal offer for each, is 30,000 AAdvantage miles for spending $1,000 on each and the standard "elevated offer" we see on each is 50k for $3k spend.

In celebration of their 20th anniversary, the Star Alliance is giving 21 people one million miles (or the determined equivalent, depending on the frequent flyer program). One set will be given out from each loyalty program in the alliance.

This giveaway is a little different than sweepstakes past, as it's not technically a giveaway. You have to earn your prize.
Here's how to enter the Mileage Millionaire competition:

Upload a picture of yourself (preferably on a blank/white background), as well as a picture of a "unique cultural experience" on the official competition website.

There seemed to be enough interest in my original post on this topic, Who Has the Most First Class Award Space to Honolulu?, that I followed up with the next most popular destination in Hawaii: Maui (OGG airport).

First Class award space in Etihad's A380 Apartment is wide open October through the end of March between Abu Dhabi and New York City (JFK).

There are two flights a day from Abu Dhabi to New York, and as of June 1 all will be flown on an Airbus A380--meaning First Class Apartments!

I tweeted this deal first from @MileValueAlerts. Follow @MileValueAlerts on Twitter and follow these directions to get a text message every time I tweet from that account. I tweet from @MileValueAlerts only a few times a month because it is designed to be used only for the best and most limited-time deals–like mistake fares–so that you aren’t bombarded by text messages.

Multiple Star Alliance carriers are offering roundtrip economy flights from cities across the United States, ranging from Los Angeles to Boston, to cities all over Europe.
