British Airways is the most direct route from Phoenix to Heathrow London so it is the flight I have used several times.
I also had enough credit for two flights in first class round trip yet how does one get this? I took a morning and started from Jan 1st through Dec 31st trying to get a flight using my points. Why did I do this, well the dates I wanted were never available so I thought I would see what dates were available. Oh and I tried coach through first class on each attempt and in all of that time frame only could I find four dates available and only in coach so I booked it and got back yesterday. I still have points but have a feeling I will never use them since this trip made me realize travel is no longer fun. You get trapped in a cabin so tightly fit with seats one can not even breathe, not to mention the air quality sucks and much too warm. Hell the food looked like cat food and tasted just about as good. Now I will say the folks working the flights were very nice, but nice does not make up for the actual physical layout of the jet. Each trip was delayed for some reason sometimes we waited to board and other times we waited while on the jet just sitting there. It states on their web site that there are no black out dates for travel, but check back often as seat open up. So right there it is stating there are indeed black out dates if no seats are available. Nope no more stinky depressing flights with British Airways for me.
