Since we live just 30 minutes drive from Newark, we have mostly flown United since we usually we want nonstop flights. As such, I managed to reach gold status on United just from leisure travel. But with the devaluations of points and the lack of upgrades on our usual routes, I have not found any value in retaining status with United so I have determined not to let loyalty stop me from getting good deals when I can find them.
We just flew to India on Emirates in business class. Not only was the in-flight experience far superior to United Polaris, it was significantly cheaper and the fare included chauffeur service on both ends.
Next month, we are flying to Greece in British Airways Club World (their business class). Again, it was a good $1000 cheaper than United and their in-flight service is competitive.
We will be flying to Bangkok for a wedding in August and found that Singapore Airlines business class is significantly cheaper than United. I know from experience that SQ business class is in a different league altogether.
