Congratulations to the First Officer on a job well done. Derry = short field; possibly poorer weather than Stansted; unfamilair, limited facilities; no push back; no replacement Captain waiting on standby; narrow taxyways with no high speed turn off. (possible runway closure due to no tiller on the FO's side). Stansted = the exact opposite with other alternatives for getting the pax back over to NI.
Well done
