Six months in Argentina came to a close, and I started to fly my favorite award I've ever booked.

The first flight was from Buenos Aires to Johannesburg on South African Airways' direct flight in business class.

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.

United has lounges all over the world. The clubs are a pleasant place to relax in a comfortable chair, use free wifi, and enjoy free snack and drinks. Here are the amenities.

Delta miles are the worst. I would rather have United, US Airways, American, and in most cases British Airways Avios. But that doesn't mean Delta miles are useless. When a good use pops up, I like to spotlight it, so that people with a stash of Delta miles can see the valuable possibilities.
