Apologies Rod, typo on my part, should of course have read VT. All their flights appear to use it, I have not noted any of them using the ICAO code
For info, the Airline table is updated regularly and all the ones passed on this thread are updated as required. I cannot delete a code entirely from the database only the data contained with it such as the airline name, IATA code etc. Therefore in addition to the data pertinent to current IACO codes the d/b also contains formerly used ICAO codes with no associated data
Many thanks
Alan
