Hi everyone once again thank you for all your advise . unfortunately when using the One world tool it seems to not allow me to go from OSL -DOH saying no availability I have put in numerous dates in Oct- Nov with the same response , Could this be a glitch ? or something more sinister as i thought NOV was a good time to do a RTW
secondly apart from OSL to DOH everything seems in order OSL-DOH-SYD-BNE-PER-ADL-CHC-THEN Surface to AKL-ICN-NRT-BKK-JFK-RIO-JFK-LAX-HEL-OSL , should i book with AA or BA for a cheaper deal for D fare and also stuck on whether to try and book it with a travel agent or BA in Oslo any tips gratefully received

Kind regards

ELO
