AA LHR - MIA Online Check In and other

Hey,

I haven't used AA since they changed the seating pitch, any comments about how cramped it feels now?

I am on a 8.05am flight next weekend, has anyone taken the early flight and comment on how it went, whether it was on time, etc??

Also - it seems AA wont allow me to pre-check in (urgh), has anyone else had this problem??

Thanks

Nick
