Now technically speaking you could call Chase to change your booking to be VCE-LHR in business then LHR-LAX in PE, but the only way to accomplish that is to just pay the fare difference and break the fare into VCE-LHR + LHR-LAX which is going to be prohibitively expensive.
For a 2.5 hr intra Europe flight on BA I can assure you it's most definitely not worth the $$ or effort.
Thank you, you saved me 4+ hours on hold with AA. For our restrictive dates of travel the difference between Prem Econ and Business was significant so we chose to stick with Prem Econ. We’ll be just fine for the quick intra Europe flight!
