We pushed CI/YYZ to secure the 2nd leg on arrival BKK 10 Dec. In fact, the 2nd shpt is deliberately skip yr holiday on 05 Dec as per yr rq as we also mentioned that "BKK fights can be heavy at times, it is very possible that this freight could be delayed, so CI cannot guarantee a timely arrival on Dec 6th or 7th in BKK."
Hence pls explain to customer about this deferred svcs as again CI is offline carrier, their flt is via JFK / TPE / BKK as recently most carriers are the peak in close to Christmas.
