I don't wish to engage in 'thread drift' or be seen to be giving investment advice . . . but quickly other 'main' stocks I bought around the same time did about as well as the airlines (ANZ - 40%; CBA - 33%; BHP - 51%; WES - 33%). However, some companies in the sector I know something about have been stellar (DWS - 165%; SMX - 115%).
Cheers
