This web-site is quite unrelaible as the data inputed cannot be verified. About a year ago there were some strange figures for delays put on this web-site for both Manchester and Liverpool Airports. The resultant figures showed that both Liverpool and Manchester were the worst for security/immigration/baggage delays in the UK.
Liverpool Airport investigated and found the an individual was making several entries each day even though it was inpossible to fly through the airport that many times in a day
On one occasion the poster had claimed a 40-minute queue for security (CCTV showed it was 12 minutes) at 06:30 in the morning and then the poster claimed to arrived back at Liverpool Airport at 08:35 (45-minute delay for immigration and 35-minute wait for baggage). It was a false claim as it is impossible to depart on a flight from Liverpool after 06:30 and arrive back at Liverpool at 08:35. On the day in question there were no delays at immigration or baggage reclaim at that time as no flights had arrived.
Several similar postings were posted on other days for both Manchester and Liverpool. Sounds like someone with a grudge.
