The 50k mile bonus offer is back on the Lufthansa card mentioned in this post until 6/30/14.

I recently had a reader ask me about the best miles to collect to get from Salt Lake City to Cozumel, Mexico. The answer illustrates the best ways to get to the Caribbean and Mexico, so I thought I'd share and expand upon it here.

Near international destinations like Cozumel can be an excellent deal on region-based award charts like those used by American, United, US Airways, and Delta.

The current best deal is this offer for the Gold Delta SkyMiles® Credit Card from American Express

Earn 30K bonus miles after you make $1K in purchases on your new Card within your first 3 months and a $50 statement credit after you make a Delta purchase with your new Card within your first 3 months.
Earn As You Spend: Get 2X miles on Delta purchases and 1X miles for all other eligible dollars spent.
Check your first bag free on every Delta flight - that's a savings of up to $200 per round trip for a family of four.

Next week I am going to Paraguay for eight days. A trip out of Argentina is necessary to renew my 90 day tourist visa, and I wanted to check the sixth South American country off my list, instead of repeating Uruguay, the easy choice. (Only four more CONMEBOL countries to go!)

I've never been to Paraguay. I'm sure tons of you have (even though until American Airlines launched a Miami-Asuncion route in November, there were no direct flights between the US and Paraguay.)

I will arrive in Asuncion and leave from Ciudad del Este. I speak Spanish.

Reader Christopher emailed me an exciting tip the other day: free oneways are possible on United awards within the continental USA and Canada. I already knew free oneways were possible on international United awards and awards to Hawaii, but this was news.

He sent me some screenshots, and I was able to replicate his findings and add some more of my own. I learned four things:

Christopher's tip: You can get a free oneway on roundtrip Standard economy awards within the US and Canada. That means three oneway Standard awards for 50k United miles.

United, US Airways, American, and Delta among others rely on award charts to determine the price of your award.

The MileValue Award Booking Service now costs $111 per person per award (for most awards--more pricing info below.) As always, you don't pay if we don't find an award that meets your needs.
