The current 4,897 ft runway at CLD
is fine. CP
never has to worry about sending its relatively low density E-170s westbound into prevailing headwinds, they'll all be headed north, south, or riding with the winds east.
For comparison's sake, EYW
has an even shorter 4,801 ft runway; not to mention an even hotter, wetter environment. US is getting E-170s out of there to CLT
(a route which also sees the larger and less capable E-175) and now DCA
is getting mainline aircraft off that runway to ATL
and now all the way to LGA
's high density all-Y 737s are now flying west against the winds to MSY
. Given that DL
, US, and WN
continue to expand from EYW
, I can only assume these flights are taking profitable payloads!
's 4,948 ft runway handles E-jets (including the E-190) all the time. Even Rio's SDU
, with it's longest runway at a mere 4,341 feet, is successfully accommodating the E-175.
Of course, a longer runway can certainly help - they can always take on more pax and/or cargo, and of course they'd fare better on CLD
's hottest days. They can also take on more fuel to fly farther. I'm merely pointing out that the runway today is not a particularly difficult challenge for the CP
