British Airways has begun transferring its Avro RJ100s to newly-formed regional subsidiary British Airways CitiExpress (BACX). BACX was formed in March by merging Brymon and British Regional Airlines. British Airways Regional is also being merged into BACX. The RJ100s were formerly operated by Gatwick-based CityFlyer, which was integrated into British Airways earlier this year. One RJ100 was transferred at the end of July, one in mid-July, one at the beginning of September, and a fourth in mid-September. All four are based at Manchester. Two more are scheduled to be transferred in October, to be based at Birmingham, with the rest following at the rate of about two a month. BACX already operates five BAe 146s. The operation of the RJs by BACX is the subject of intense labor negotiations within BA.
