I will be starting an AONE4 ex CAI next week issued on BA ticket stock via the online booking tool and a phone call to BA in UK when there was the currency devalutaion
Did the bare minimum of flightst get a valid routing as I wanted it ticketed asap for obvious reasons .
After my initial flight next week from CAI to LHR I intend to make significant changes involving a reissue for the 125USD plus any differences in taxes and surcharges etc

Should I be concerned in the light of the OW freezing of tickets ex Eygpt ....
I assumed that the rules that were current at the time of purchase and issuance would apply retroactively .

And if there are no fares currently published ex CAI on BA what does that mean if I tried to make the changes now ie NOT change the first flight CAI-LHR but add some stops after that etc
Would they just charge the reissue fee or is it simply not possible ?

Does anyone have experience of this yet ?

Many thanks and happy holidays and safe flying
