Just to add....
Did this route last year transiting to Cancun,
No major problems, quite happy with the service
out and back, friendly and professional.
No AVOD on way out but they were still in the middle of retrofitting
the 75x (I don't know which type it was :-) )However we did on the
way back.
All in all pleased with them overall, Newark is fairly easy to navigate as
well and was pleasantly uncrowded. TSA and Border sec were also far
more pleasant to deal with than Atlanta.
Only reason we used Delta this time was the changes to
baggage allowances as Cave diving rigs weigh a bit! We're
actually direct Manchester-Cancun with Thomson in October
as they're now the cheapest option as all the US carriers have revised
their baggage pricing (Bah! Humbug!)
