I accidentally canceled the contract for the Southwest Desert Gold livery that you receive when reaching level 44 in MSY. Double tapped by mistake and second tap hit the cancel button.
Is there any way to recover that one, since it’s not a livery one can buy, I think, and not available as regular flight on MSY-LAX after you’ve ‘earned’ it.
I don’t think it’s possible, but if you email the devs at support@flyboys.games then they may be able to help you or at least advise you on if the contract can be recovered or if it’s lost for good.
Once you cancel it you can’t undo it, your going to have to buy it again if it is regular, if it’s special livery (like you mentioned it) once you cancel it the decision is final.
Time to implement an ‘are you sure you want to cancel this contract’ option then with those specials. Though that might not solve my issue.
Dropped a mail though, see if something can be done in the background…
If you enter “Contracts” menu and try to cancel, it asks for confirmation, but under the default airport screen, it doesn’t. It should always ask for confirmation… I lost a lvl 10 contract the same way you did 
Just an update — Flyboys support has restored the DHL B77LF SYD–HNL contract that I accidentally deleted when I reached level 32 in SYD for me. Took around 4 days, Huge thanks to the Flyboys team for the quick help and great support!
