mockingjay - you will probably find your MP not too bothered about 261 (particularly at the moment!) as it really isn't a vote winner however your MEP may be a little more interested as it stems, after all, from the EU.
The airlines (Jet2 in particular hence on this thread) have put a lot of effort into defeating UK claims via local, county, high, appeal and supreme court action however they (like many others) have put little or no effort, into tackling the law at source. Indeed if it were not for the Gibraltar EU fiasco the law would probably be made even tighter.
In 2012 my MEP knew nothing about 261 - he actually departed in the last election and I then had to 'brief' the new MEP - unfortunately whilst she has contacts on the Transportation Committee she is not on same so my route of communication is diminished.
The airlines have generally relied upon the CAA/NEB representing their wishes however as can be seen with regard to press releases over the weekend/today the CAA appear to be giving into public pressure.
