How about this method:

1) go to Great Circle Mapper

2) copy this and paste into the window "paths":

PWM-MHT-BOS-PVD-BDL-HVN-ISP-JFK-LGA-HPN-ALB-ITH-BUF-PIT-EWR-PHL-BWI-DCA-IAD-CRW-LYH-DAN-ROA-RIC-ORF-PHF-GSO-CLT-CAE-HHH-ATL-HSV-BHM-MGM-MOB-TLH-TPA-MCO-PBI-FLL-MIA-RSW-EYW-JAN-GTR- MEI-MSY-AEX-LFT-BTR-MLU-SHV-BPT-HOU-EFD-IAH-CLL-GGG-TYR-DAL-DFW-ILE-AUS-SAT-HRL-LBB-AMA-MAF-ELP-ABQ-COS-DEN-OKC-TUL-XNA-LIT-MEM-TYS-SDF-LEX-CVG-CLE-CMH-TOL-DTW-DET-IND-SBN-MDW-CGX- ORD-MKE-MSN-MSP-MOT-OMA-MCI-STL-BIL-BOI-SEA-PDX-EUG-SFO-OAK-SJC-SMF-FAT-MRY-SBA-BUR-LAX-PSP-ONT-SNA-SAN-TUS-PHX-LAS-RNO-SLC

3) click "display map"

Much easier than a long link!
