Narrative:

We departed VFR from chicago meigs (cgx) to waukesha (ues). After departure contacted chicago approach for VFR advisories and climbed to 6500 ft. Chicago approach discontinued advisories at the end of their airspace and suggested we contact milwaukee approach on 119.65. We called mke approach on the suggested frequency and were told to expect advisories in 15 mins. At that time we were currently 12 mins from our destination and continued without RA's. We began our descent into waukesha. As we past through approximately 4600 ft the PNF noticed an airliner about 1 mi off at the 3 O'clock position that would pass underneath us. We continued the flight and landed at waukesha where we were asked to call milwaukee approach. Milwaukee informed us that the airliner had an RA on us and descended in response to the RA. This issue could have been prevented by: milwaukee approach providing RA's, rather than delaying them. Better vigilance by both pilots in both aircraft to see and avoid. Vectors by mke approach of the airline to avoid our path once we began the descent (unless they had us visually).
