Bos-tlv $554 is dead, but ord-tlv is now available for $593 on AC, $599 on DL, and $601 UA. HC nyc-tlv-nyc (-ord) is $713. Not as lucrative as bos was, but what can you do? Plenty of $44 nyc-ord dates available.
Same pricing holds true for Baltimore/Washington. Iad/dca-tlv is also $593 AC, $599 DL, and $601 UA. HC is the same price as above.
