VT,
Not too sure exactly what you want to know, but from the ENE you have Leeds and Manchester to navigate/avoid. POL VOR DCT Burtonwood vrp would put you nicely in position, Leeds would probably pass you to either LPL, Warton or Blackpool from POL. You shouldn't have any need to talk to Manchester, just watch out for the class A/D and Pennines combo.
Barton is near your track and can get busy.
LPL itself should be pretty straight forward. They do get busy, but have plenty of GA activity. The field is very easy to spot, Mersey south and the mushroom tower ( can't miss it ) to the North, just remember that there is the old Speke field very close to the WNW.
Good GA parking, but as I remember, not the cheapest place to land. (Had a very expensive night landing there once
)
If there is anything more specific I let me know. Have a good trip either way.
Best Regards,
LF
