TWA isn't the only US airline there anyway. CO has two daily EWR-TLV flights and just began code sharing with Emirates, a much stronger and powerful ally
for the region than Kuwait Airways and Royal Jordanian, both of which code
share with TWA.
I think TWA will continue to do well in the region (Cairo, Riyadh, Tel Aviv)
even if CO enters the Amman market. Both airlines have good service and
little in the way of overlap. Delta and CO have proven that you can operate
successfully across the Atlantic from New York without getting into each
other's way too much.
