Narrative:

WX was below freezing for morning departure. Normally, aircraft is shot with type I fluid at gate before crew arrival. Aircraft was boarded at gate of another air carrier, as all ours were full. Deice was to be done after pushback and taxi to our gate area. After start and taxi, aircraft was configured and deiced (only thin frost). Ground crew made no attempt to talk to us on interphone. We did not get any of the normal communications per a 'normal' deice. We dismissed the lack of communication. We knew type of fluid and start time as visually observed. SOP is for ground crew to communicate -- type of fluid, time started, and aircraft clean before departure. I was lulled into complacency by attitude of ground crew and fact that when aircraft is deiced before crew arrival, usually don't get or see that information. Approached this procedure as something that should have been done before our arrival and 'removed' myself from process. Upon investigation, found that ramp should always give deice information to crew even if done before crew's arrival. Ways to avoid: always approach deice in same manner. SOP is SOP -- even if no precipitation and only light frost on aircraft. It does not matter what level of contamination -- if it's not clean, deice per SOP.

Title: MLG CREW WAS IMPROPERLY DEICED AFTER TAXIING TO THEIR GATE AREA.

Narrative: WX WAS BELOW FREEZING FOR MORNING DEP. NORMALLY, ACFT IS SHOT WITH TYPE I FLUID AT GATE BEFORE CREW ARR. ACFT WAS BOARDED AT GATE OF ANOTHER ACR, AS ALL OURS WERE FULL. DEICE WAS TO BE DONE AFTER PUSHBACK AND TAXI TO OUR GATE AREA. AFTER START AND TAXI, ACFT WAS CONFIGURED AND DEICED (ONLY THIN FROST). GND CREW MADE NO ATTEMPT TO TALK TO US ON INTERPHONE. WE DID NOT GET ANY OF THE NORMAL COMS PER A 'NORMAL' DEICE. WE DISMISSED THE LACK OF COM. WE KNEW TYPE OF FLUID AND START TIME AS VISUALLY OBSERVED. SOP IS FOR GND CREW TO COMMUNICATE -- TYPE OF FLUID, TIME STARTED, AND ACFT CLEAN BEFORE DEP. I WAS LULLED INTO COMPLACENCY BY ATTITUDE OF GND CREW AND FACT THAT WHEN ACFT IS DEICED BEFORE CREW ARR, USUALLY DON'T GET OR SEE THAT INFO. APCHED THIS PROC AS SOMETHING THAT SHOULD HAVE BEEN DONE BEFORE OUR ARR AND 'REMOVED' MYSELF FROM PROCESS. UPON INVESTIGATION, FOUND THAT RAMP SHOULD ALWAYS GIVE DEICE INFO TO CREW EVEN IF DONE BEFORE CREW'S ARR. WAYS TO AVOID: ALWAYS APCH DEICE IN SAME MANNER. SOP IS SOP -- EVEN IF NO PRECIP AND ONLY LIGHT FROST ON ACFT. IT DOES NOT MATTER WHAT LEVEL OF CONTAMINATION -- IF IT'S NOT CLEAN, DEICE PER SOP.
