Hey quitinger,
im trying to be positive here cos i got a call to do a re-medical checkup as well, just to get my surgeon to certify and rite a note to cx mentioning that the surgery i'd gone through before is definitely not going to affect my duty as a future flight attendant, if accepted by the airline.
another fren whom i met at cx interview and who's been flying with another airline for years, received a call for a re-medical check-up too.
i personally feel that for the fact the airline is willing to invest on you again, to come by for another re-med check-up, shouldn't we feel happy or at least pleased about it & not have negative thoughts instead? bearing in mind that each time we visit the airline's appointed clinic, we're adding on to their expenses list...let's just hope that it's good news to receive another call for 2nd check-up from them and see it as getting us a step closer to being selected
so, keep your spirits up and shun away all the negativity...
