Valid routings are :
FROM HOU-CO-DFW-CO-MEM-CO-HOU-
OR FROM HOU-CO-ATL/BNA/CHI/CMH/DFW/
IND/MKC/MSY/SDF/STL/FLL/MEM/ORL/RIC/
TPA/DAY-
TO CO-BOS/WAS-CO-SAV*
OR TO CO-CLE-CO-EWR/NYC-CO-SAV*
OR TO CO-WAS-CO-CLE/EWR-CO-SAV*
OR TO CO-DTT-CO-EWR/NYC-CO-SAV*
OR TO CO-CLE-CO-DTT-CO-CLE-CO-SAV*
so it looks like you could at least go IAH-EWR-SAV and if the timing works out could route through DCA, CLE, ATL, etc. Just a quick pricing on CO.COM came up with $251 for IAH-DCA-EWR-SAV-EWR-IAH. IMHO I'd forego the 200 miles extra and just do IAH-EWR-SAV-EWR-IAH and time the flights so that you're on one of the widebodies for upgrading purposes. Either way you're on an RJ to SAV. There's no getting around it.
