American Airlines releases a ton of award space on its routes to Hawaii at the last minute.

On almost all of American Airlines' routes from Los Angeles to the four major Hawaiian islands and Dallas/Fort Worth to Oahu and Maui, there is award space for 4+ people in the next few weeks.

If you live in Southern California or North Texas, this is a great chance to use as few as 12,500 Avios per person per direction to get to Hawaii during high season when the weather is a perfect 85 degrees and sunny.

If you live somewhere else

Three weeks ago I got an email from AirTran A+ Rewards with the subject "Get 750 Rapid Rewards Bonus Points."
The email explains that Rapid Rewards and A+ Rewards, Southwest's and AirTran's loyalty programs will merge on November 2, 2014. (Southwest acquired AirTran in May 2011.)
If you verify your A+ and Rapid Rewards accounts to make that combination easier on the airline, you can get a quick 750 Rapid Rewards, worth about $11 in free flights.

US Airways miles can get you to the Middle East and Indian Subcontinent on Qatar Airways flights in Business Class.

American Airlines and US Airways are currently offering huge bonuses on transfers from SPG Starpoints.

British Airways has a unique, distance-based award chart that can provide fantastic value for short-haul flights.

Both Chase Ultimate Rewards and American Express Membership Rewards transfer 1:1 to British Airways Avios.

British Airways has access to all American Airlines "MileSAAver" award space. Furthermore, on some routes British Airways actually charges fewer miles for the same flight than American Airlines.

Unfortunately, using ba.com is not as straightforward as using aa.com.

Until July 31, 2014, you can transfer 20,000 SPG Starpoints to 30,000 US Airways Dividend miles.

This promotion is identical to the current promotion to transfer 20,000 Starpoints to 30,000 American Airlines miles, which makes sense since US Airways and American Airlines have legally merged.

Yesterday I said about the American Airlines promotion: "it's July 2nd, and I think we can probably declare this the best miles deal July will see!" Of course, such a statement was disproved in less than a day because I consider the US Airways promotion slightly better.

How many Starpoints

Frontier is offering 20% off regular and sale fares for domestic travel July 12 through December 12, 2014. Blackout dates of November 20-26, and November 28–December 2, 2014 apply. You must purchase by 11:59 PM ET July 4, 2014 with promo code RGIFT2U to lock in the savings.

Frontier frequently offers 10%+ off its fares through two or three day sales, but I have not seen 20% off yet.

When comparing the price after the 20% discount to other airlines' fares, remember that Frontier now charges for carry ons and checked bags.

Overnight, I wrote about the current Starwood/American Airlines promotion: for all of July, 20,000 Starpoints will transfer to 30,000 American Airlines miles.

I gave the facts in this post, but I was called out in the comments for not analyzing the promotion. Said DH:

"Is this offer an indication there’s an AA devaluation right around the corner? If so, is this transfer still a good idea? Starwood points are really valuable, and I doubt devalued AA miles would be anywhere close.

Until July 31, 2014, you can transfer 20,000 SPG Starpoints to 30,000 American Airlines AAdvantage miles.

It's July 2nd, and I think we can probably declare this the best miles deal July will see!

American Airlines' non-oneworld partner, Etihad, has fantastic award space to the Middle East, India, and the Maldives.
