That's $1670 plus the credits, right? OK. so please explain why you think that a Tango fare customer is going to be able to easily upgrade
You are aware that on the longhaul routes, the load factory is rather high? There is an ongoing issue of overbooking.
Then there are going to be the aeropoint addicts who will want their full points and will fly in flex and will also assume that they will stand a better chance of an upgrade. However, more likely will be the folks in PE looking to upgrade and they will occupy a higher part of the pecking order.

I appreciate that you like living life on the edge, an adventurer, willing to try new things like red tortilla chips vs yellow, or wearing those odd fitting boxer briefs from HM which I can't wear because I am too fat and too old. However, it seems to me that it is very, unlikely you will score the upgrade from a Tango fare. In plane language you are deluded. (Yes, I know it should be plain, but this is an air travel forum and I am trying to show off my grasp of language, and offer a witty pun, which I shouldn't have to explain, but I just know someone will notice). Of course, I could be wrong. It wouldn't be the first time, but I just think you are setting yourself up for heartbreak. Unless you have an ability to charm the system. Everyone's going to be upgrading, so it's going to be difficult to get one. What am I missing?
