Narrative: I wanted to write an FSAP and PDR concerning a situation that occurred this morning. I'm very very upset and concerned with this situation and hope that the appropriate actions are taken SYSTEM WIDE to make sure that this doesn't happen again. I've spent over 20 years trusting our de-ice crews and after today; that trust is gone. I believe; because of this incident; we ABSOLUTELY NEED to go back the way of doing a pre-contamination check of the wings prior to takeoff; not just look at the nose! We arrived to the aircraft this morning which had been sitting on the gate since the previous morning. It had approximately 24 hours of ice/snow; etc. accumulation due to a cancellation the day before. Operations was advised of the need for de/anti ice. We pushed off the gate and because of the accumulation; it took almost an hour to deice with Type 1; and an additional 30 minutes for Type 4. Iceman said that deice was complete and relayed the required information. Shortly after I received a call from the lead Flight Attendant; letting me know that a deadheading pilot (non-company) had rung his call button to advise us that there was still frozen precipitation on the wing. I immediately went back to verify and was incredulous at what I saw. All across the top of the wing; from wing root to about 7-10 feet from the fuselage was a layer (on both wings!) of frozen adhering precipitation. Again; this is AFTER iceman told us that the deicing was complete. This can be corroborated by the deadheading pilot.I went back to the cockpit and immediately called iceman and told them of the situation; and that we needed deicing again. The driver (whom I was communicating with) had said that he couldn't see the top of the wing; but he would relay to the sprayer (he had mentioned that he had 30 years of experience at some point in our conversation). They proceeded to give us a 2nd de/anti ice and when done; came back with the required information. Having lost all trust with the individual that had deiced us twice now; I requested from the 30 year; experienced driver to switch positions with the bucket sprayer. He said no problem. After about 20 minutes; he came back to us and let us know that the aircraft was now clear; but that he had to spray the tail again. This is unacceptable.I'm no expert on when an A320's performance will be degraded to the point of a hull loss; but I will tell you I would have personally blown one of the slides to get off the aircraft if a crew would have continued to the runway with our situation. To say I'm extremely dismayed at the situation would be an understatement.


Second narrative: [Report narrative contained no additional information.]


Synopsis: A319 flight crew reported their aircraft had been sitting at the gate since the morning prior and had 24 hours of accumulated ice/snow. The flight crew noticed after the de-ice procedure that ice remained on the wing from the fuselage outward about 10 feet.
