There is:

widely available
underpriced
economy award space
for two passengers
for all of 2014
to Australia
with the opportunity to stop in Hawaii for a few days in either direction.

If you have 75,000 American Airlines miles and about $100, you can fly a roundtrip award from the United States to Australia on almost any day you want this year.

Yesterday I posted "Not April Fools: Delta Has the Best Award Space to Asia I’ve Ever Seen."

I showed screen shots of how incredibly available--every day for months--Saver award space was on Delta flights from the west coast to Asia.

The offers for the cards listed in this post have expired, so their links have been removed.

Update 1/16/14 at 1:59 PM Hawaiian time: All the calendars shown are for one-passenger searches. There is almost no space for two passengers on the same cabin on the same flight.

Delta infamously offers the least Saver award space of any US-based airline.

Frontier has announced an 18% discount on domestic flights bought by January 16, 2014 and flown by March 12, 2014 with promo code HURRYHURRY. (Blackouts: February 13, 14, 15, and 17)

This 18% discount does not apply to Frontier's international destinations like Jamaica, Mexico, Costa Rica, and the Dominican Republic.

To get to those places, your best bet is to redeem 15k Frontier miles each way.

I’m very excited to announce the first MileValue dinner since October on Saturday, January 25 at 7 PM on Oahu, either in Waikiki or Honolulu.

As a special treat, I've confirmed the attendance of Rene from Delta Points. Rene is the go-to expert on all things Delta from status, to the myriad credit card offerings, to redemptions, to aircraft, to getting bumped, to... you get the idea.

Delta and SkyTeam are major players from HNL.

Delta is well represented at HNL.

Virgin Atlantic is back with another incredible discount on its economy awards to the United Kingdom.

For about 13k miles plus $100 one way, you can go from Boston, New York, Washington DC, or Chicago to London, Manchester, Glasgow, or Edinburgh.

For about 16k miles plus $100 one way, you can go from Miami, Orlando, Las Vegas, Los Angeles or San Francisco to London, Machester, Glasgow, or Edinburgh.

Roundtrip prices including miles, taxes, and fuel surcharges.

United announced a massive devaluation of its miles on October 31, 2013 to take effect for awards booked February 1, 2014 or later.

The Frontier Airlines World MasterCard® recently increased its sign up bonus to 40,000 bonus miles after spending $500 in the first 90 days.

The sign up bonus is extremely generous for such a small minimum spending requirement, and the miles go a long way because of Frontier's cheap award chart.

Domestic flights--including to Alaska in the middle of the summer--are only 10k miles each way.
