One things to watch out for with the Level options is the class of service vs. the type of reward you are seeking.

I was looking to book SFO-BCN and after seeing reports that IB flights are showing up on AA.com, so I opted to check it out for a business/first award.

I was hoping to see IB flights but instead saw Level flights to LAX from BCN. There is no business/first on the flight. But there would be first to/from LAX from SFO. Totally not worth it.

Unfortunately I have to stick with my flights via LHR that I was able to snag on a J saver award back in February. Trying really hard to avoid the taxes and fees at LHR but don't want to make the trip any longer than it already is going to be at this point.
