CO has an incredible frequent-flyer programme. As soon as you make a reservation, your OnePass number is entered into the system and if you are an Elite, you are automatically queued for an upgrade...no coupons, no calling 24/48/72 hours in advance as on DL
. I have been just Gold on CO
for 3 years, fly at least once a month and have sat in coach maybe four times. Their Y class catering is appalling (those meatloaf sandwiches heated in plastic bags!!!), but F is very good, and I have found the crews invariably happier, kinder and friendlier than on DL
. One sour note is they don't use widebodies for as many flights as DL
does; I have been on far more 75s and 73s than I would like. But overall we have found them far superior to Delta, to whom we were loyal for years.
