Regional airline Air Southwest is launching a new development plan as it continues to grow from its base at Plymouth City Airport.
The first step in the plan will see a new flight code introduced on all of the carrier’s flights from Sunday (May 31st).
Instead of the current WOW prefix, Air Southwest’s flight numbers will begin with the letters SZ.
Managing director Peter Davies said that the airline needed to work more closely with other carriers in the future.
"For us to do that we needed a two-letter code assigned by the International Air Transport Association," he explained.
"The only difference for customers is that from May 31st when they are catching an Air Southwest flight they will need to look out for SZ rather than WOW on the departure board."
Air Southwest operates flights to 13 cities in England, Scotland, Ireland and the Channel Islands and is the largest operator out of Newquay Airport.
Earlier this month, the airline celebrated the launch of twice-daily flights to London City Airport from Newquay and Plymouth.
