Narrative:

After departure from cgx, clearance was given to climb to cruise altitude of 5500 ft MSL. Upon reaching 5300 ft MSL, I was informed that I was leaving cgx airspace and should contact gyy since I was going to turn to on course heading (094 degrees) for home base (ttf) over gyy. I made initial call-up to gyy and reported position and altitude of 5300 ft climbing to 5500 ft. Gyy approach asked me if I had been talking to ord. I informed them I hadn't then realized my mistake. Gyy gave me ord frequency and I contacted them immediately reporting position and altitude. Ord requested my destination and intentions to which I replied I was descending as fast as possible to get out of class B airspace. Ord asked if I had a class B chart, I replied I had only a sectional. After approximately 5 mins of ord control, I was handed off to sbn. Obviously I should have kept myself clear of class B, and I am the final one responsible for my flight. However, meigs handed me off to gyy after clearing me for 5500 ft. This was a mistake on my part, and was realized as soon as gyy mentioned ord. I immediately began a descent to clear class B airspace as I was contacting ord.

Narrative: AFTER DEP FROM CGX, CLRNC WAS GIVEN TO CLB TO CRUISE ALT OF 5500 FT MSL. UPON REACHING 5300 FT MSL, I WAS INFORMED THAT I WAS LEAVING CGX AIRSPACE AND SHOULD CONTACT GYY SINCE I WAS GOING TO TURN TO ON COURSE HDG (094 DEGS) FOR HOME BASE (TTF) OVER GYY. I MADE INITIAL CALL-UP TO GYY AND RPTED POS AND ALT OF 5300 FT CLBING TO 5500 FT. GYY APCH ASKED ME IF I HAD BEEN TALKING TO ORD. I INFORMED THEM I HADN'T THEN REALIZED MY MISTAKE.
