Tripe??
CUN is far quicker than MAN to initiate single-runway operation on its second runway when needed. From experience, after an abort. Which is surprising when one reads all this pro-British pro-MAN tripe.
And MAN are far more panic-liable when it comes to closing a runway due to suspected FOD contamination or runway damage, or indeed late runway clearance by landing a/c. Primarily not ATC, but the airport "authorities". And those stupid "leader" drivers haven't a clue how to bring in a jet. They drive at a pace that requires constant braking, brake-heating, and steering difficulties. They need to learn to drive airside.
As for the airport itself, it is inferior to many 3rd world places in terms of security, ground handling, taxiways, terminals, and public access. The taxi access to T1 and T2 is congested and tricky, prone to start-up delays, taxi- clearance delays, and taxi-in hold-ups.
The place stinks. Can't wait to retire next month.
