It should actually be
CS and not
CM -- a
KVS Tool update will be released shortly:
[KVS Availability Tool 7.2.0/Diamond - Awards/SkyTeam/US-AF]
Code:
IAH Houston George Bush Intercnt'l TX US [KIAH]
AMS Amsterdam Schiphol NL [EHAM]
TUE 04 Jun 2013 | 1 Seat
Carrier Flight From Depart To Arrive St Availability
--------- ------ ---- -------- ---- -------- --- -- -------------
KL 662 IAH 15:10 AMS 07:30 +1 CS+ WX/ YX+
DL.com
will display this flight if you search Awards by Schedule.
Delta.com shows this flight in search by schedule but then gives you an error. Called Delta and they mention there is no such availability. So my point is that KVS is showing a flight available that is actually not bookable.
