So I had posted up thread about my Hawaii trip and decided that I would just pay for premium economy on the way back since I really wanted the meal service and better seat but just for giggles I decided to request s 500 mile upgrade ( which I was told here was nearly impossible to get) for my LAX-HNL flight tomorrow and lo and behold, it just cleared within the last hour. I did have to pay $240 as I don't have any stickers to my name. I'm actually sorta excited to try it out although yes I did read that it is nothing special but I am connecting at LAX from East Coast so after 5 hours in economy even though got MCE, figured it be worth the price to have a wider more comfortable seat for the next 5 hours and a meal. So yeah, it looks like there is still upgrade space available on EF.
