Updated June 3: The Asiana miles showed up today, meaning the transfer took 14 days. My last transfer in September 2014 took 17 days. In the interim, I've decided not to book Lufthansa First Class from Europe to the United States in June, but the Asiana award chart is so good that I don't mind have 60,000 points on hand. That's almost enough for Business Class one way USA to Argentina (35k) + First Class USA to Hawaii (27.5k).

You can book Lufthansa First Class for 50,000 Asiana Club miles--40,000 Starpoints--one way.

Today only: Frontier is offering a last-minute fare sale for June travel. Fares start at $19 one way!

The sale is valid for bookings made by 11:59 PM ET today only (June 2) for domestic, nonstop travel mostly on different dates specified by each sale route. Unlike previous sales, which were only available for Tuesday, Wednesday, and Saturday travel, these deals are available all seven days of the week.

Here is the sale page and restrictions.

Starwood Preferred Guest has two summer promotions that should be stackable, and for some people, the value of the promotions will make mattress running a viable option.

The first promotion--Make It Count--offers 1,000 bonus Starpoints for each eligible 2+ night stay that includes at least one weekend night. Eligible stays must be completed by August 31, 2015.

Last October, I ditched my apartment in Waikiki for a renewed stint of vagabonding. Most people just don't get it.

"OK, but where do you live?" It's equally true that I live wherever I am at that moment or nowhere.
"Where's your home base?" Nowhere.

I've learned that I like to stay in a place for at least several weeks to figure out its rhythms and my favorite restaurants, sports activities places to go out, and new friends before I move on.

This is the ninth installment of a round-the-world trip report that started here.

Update June 1 at 9:12 AM ET: Club Carlson has tweeted that the benefit will still be bookable until 11 PM CT tonight, so book, book, book. I burned all my points yesterday on speculative two night stays in Lithuania and Chennai. I can cancel them and get the points back if my plans change.
