score:8
Liverpool airport does not have any facilities for airside transit.
I have a connecting flight, do I have to go through security again?
If you are arriving on a flight into LJLA and are departing again on another flight you will need to exit through the arrivals area and proceed to security again for your departing flight.
Liverpool John Lennon Airport recommend that passengers arrive at least 2 hours prior to their scheduled time of departure.
That last part is probably quite optimistic. You should have much more buffer between the two flights.
