Passengers scheduled to fly to the Isles of Scilly from Land's End Airport are still departing from Newquay.
No planes have flown from Land's End since before Christmas due to a waterlogged runway.
The airport is, after the closure of the Penzance heliport last year, the only surviving air link to the Isles of Scilly in west Cornwall.
It has been constantly plagued by waterlogging issues during the very wet end to 2012.
A spokesman for the Isles of Scilly Steamship Company said Skybus flights will return to Land's End as soon as conditions allow and the situation is being reviewed on a daily basis.
He said: "We are still using Newquay for the time being while we trial some new matting at Land's End and explore longer-term solutions.
"This does involve longer flights but we have structured our schedules to take account of this and we are evaluating conditions on a daily basis."
"Despite the adverse weather, including almost 50% more than the average rainfall at Land's End and 28 days of rain during December, we successfully transported all passengers and freight to and from the islands for both Christmas and New Year and our staff continue to go the extra mile for our customers."
Skybus will fly to Scilly six days a week in good weather.
