You know you&rsquore in good hands when your driver doesn&rsquot have to drive down to the airport to drop you off. No, Emirates send around a Mercedes, at their expense, when you fly beyond the business class curtain. It&rsquos a Boeing-777 on the short Delhi-Dubai sector as well, so even though the business class section is large, there&rsquos no line at check-in. The Emirates lounge at Indira Gandhi International Airport in Delhi is its own and well-managed, and I&rsquom in a pretty mellow mood by the time I board. A glass or two of champagne and a movie and a bit of a snack later, I&rsquom in Dubai. So far, so good, but the real test is to come. Houston, that fair and oily city in South Texas in the US, is a full sixteen-and-a-half hours away. Now that&rsquos a test.
