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

Mashable readers: Welcome to the best blog on redeeming frequent flyer miles. The way that I've traveled to over 20 countries this year and spent nine months abroad is by signing up for credit cards and using the miles to book business and first class awards.

Here is a post that explains to beginners what I do and why I do it.

Mashable readers: Welcome to the best blog on redeeming frequent flyer miles. The way that I've traveled to over 20 countries this year and spent nine months abroad is by signing up for credit cards and using the miles to book business and first class awards.

Here is a post that explains to beginners what I do and why I do it.

There are currently four stackable promotions related to US Airways miles.

Barclay's is offering US Airways Premier World MasterCard holders up to a 50% rebate on redeemed miles between and November 30, 2013 up to a maximum of 30,000 rebated miles!

This is an incredible deal, and complements Monday's Share Miles deal that I called "the best opportunity to buy miles all year."

Are you eligible for a 50% rebate on your US Airways awards?

We're three months away from Christmas. If you know you want to visit family over Christmas, and you haven't yet booked your ticket, it is not too late to get home for Christmas for free.

But you have to start planning now. What's the plan?

First let's talk about how you shouldn't try to get home for free.

US Airways emailed me the following yesterday:

It's some slick marketing, but I won't be taking advantage of any of the "new" benefits. I have a US Airways Premier World MasterCard, so you'd think I'd be excited, but I'm not.

Why won't I be taking advantage of any of these generous-seeming new benefits? Let's go through the "additional travel benefits":

Zone 2 Boarding and First Class Check In: While nice, these aren't new and have been benefits of the card for a while.

Update: Several--if not all--of these offers have expired.

This post will explain how a couple can get 10 nights for free at a top-tier hotel in Hawaii plus First Class roundtrip flights all for about $150 per person total.

The balance in my US Airways account was practically blinking like a giant Las Vegas neon sign.

120,368!

120,368!

120,368!

As luck would have it, 120,000 miles is the exact amount needed for a roundtrip first class award to North Asia. United charges 140,000 miles for the same award.
