Interpret change planes vs stopover
 

On May 24,2012, will be flying CO, MAD-IAH on Flt.# 63. The schedule lists a 2hr & 15 min. layover in EWR with a "change of planes" from a 757-200 to a 767-400ER.

The other schedule lists same 11:35 am departure time from MAD-IAH with a 3 hr. 10 min. "STOP" in EWR. and no further info. on the aircraft to IAH.

Am I to assume that it will be the same flat bed 757-200?

I called CO. and she said "possibly", but they" could" change aircraft.

What is your experience?

Recent Experience MAD-IAH
 

CO63 (MAD-EWR) is a 757 aircraft, arriving B terminal. CO1644 (EWR-IAH) is a 767 departing 4:30pm terminal C. Since CO63 arrived late, we missed that ticketed connection.
However, we were rescheduled at EWR on CO63 (EWR-IAH), departing Terminal C at 5:30pm.
It was also a 757 but not the same aircraft which flew us from MAD.

If it is still a 757-200 then it will be the same config (there is only 1 with CO these days) , though not necessarily the same exact aircraft.

It isn't completely uncommon for the wide-body aircraft scheduled to operate between IAH and EWR to get swapped if there is a maintenance issue or something similar that demands such an operational change. It happens every now and then.

Also, if you book the CO63 flight book it as MAD-EWR + EWR-IAH rather than MAD-IAH. Booking a direct flight means fewer miles and assorted other issues that are generally not worth the $2-5 savings in fees.
