Yes, but the trade only window runs for 24 hours. All other tradeing requires rsv coverage to be adequate.
The flying that hits the pot from this process is distributed to the rsv pilots when they are bidding their days off. Almost every month there is enough trips to create full lines and rsv pilots can avoid rsv by bidding the leftover lines of trips.
It works good when the server keeps up with all the tradeing.
Christmas becomes a problem because everyone trades out of their Christmas trip, and it leaves more Christmas trips in the pot than available reserves. Then the company has to pay extra to get guys to pick up a Christmas trip.
It makes since to everyone not senior or on a negotiating committee. Those types think holiday pay is dollars in a contract not steered towards them. Get your first raise from the company and your second from your peers.
