I believe that the only ARN service CO has is codeshare service with KLM from AMS. We've been using SAS going to Sweden and crediting the miles to UA. The schedules are much more convenient and the fares seemed to be a LOT less than on CO.
If you must buy on CO, keep checking the fares ans they usually have sales for summer travel some time between December and February. I'd expect to pay at least $650 each from EWR in June.
