no threat
Ryanair are operating routes from BRS that wouldn't work from BOH and they are operating routes from BOH that make sense only from BOH - possibly pulling people down from BRS/Wales and west country too. The two should be complimentary - remember that BRS can cater for wales and Ryanair are anti Cardiff. BOH will appeal to southampton residents/isle of whight and some west country... ryanair know what they're doing.
