Sale of London Routes Helps TWA Make $336.9 Million: Trans World Airlines Inc. said it made $336.9 million in the second quarter, mainly because its sale of prized London routes erased what otherwise would have been a loss. TWA said its $53-million operating loss was more than offset when the carrier sold London routes out of New York, Los Angeles and Boston to American Airlines for $445 million. TWA’s earnings for the quarter compared to a net profit of $103.4 million for the period a year earlier.
