It is difficult to comment without knowing the methodology used. However, Manchester is like three airports in one with all three terminals offering a completely different customer experience from each other. It is entirely possible to have a good journey departing from T2. I also find T3 a pleasant space at quieter times when it is not rammed. T1 is unlikely to win any accolades for departures. In the case of incoming passengers, all three terminals are capable of offering a very quick and painless arrivals experience, and they frequently do. Customers appreciate that and will mark accordingly. I've had far more good experiences using MAN than bad ones since covid restrictions were listed. We're all familiar with the regular issues, but the important stuff usually works. They just need to replace or re-apply barcodes to those ancient trays at security which consistently "fail to scan". Really frustrating when you've prepared everything correctly yet still get delayed by one of those.
