It's possible to get cheap fares but you have to play around in the reservations and keep looking constantly to snag last minute low prices, sometimes even within a day or two of travel---so only works if your plans are relatively flexible. In September I got Bmore to Bridgeport, CT for $37, NYC back to Bmore for $37. Last weekend Bmore to NYC on Acela for $83 and Bridgeport, CT back to Bmore for $56. I might have booked the ticket to Bridgeport in September a week or two out, but everything else was booked within 1 or 2 days.
