I will be leaving for the Philippines and bought an iLugger bag. And I'm not sure if the dimensions will fit through the carry-on scanner. Has anyone successfully traveled with a 20" iMac? Did you encounter any problems? Will Northwest Airlines allow you to take a 20" iMac with you on the plane? The OVERALL dimensions are withing TSA specifications. But its a little awkward because it is square and not rectangle. So I'm unsure it will fit through the rectangular scanners. So please let me know if anyone has been able to transport their 20" iMac with you as a carry-on when travelling. Thank you very much!!!
