The 330 order was converted when TWA ordered the 318's. For TWA's purposes renewing its short-haul fleet is far more important at the time than getting new overseas aircraft... a large portion of the trans-atlantic routes have been cancelled (remember Karabu) for various reasons, mainly they weren't making money. TWA has been able to supplement and upgrade their long haul fleet through leaseback deals with GECAS and ILFC.
