Strikes 'will not affect' Southampton and Bournemouth airports
Transport bosses across the South of England have said they do not expect UK Border Agency strikes to affect passengers on Thursday.
Hundreds of immigration and customs officers are due to join the public sector strike over pension changes.
Southampton and Bournemouth airports said they did not expect any impact, as did ferry ports in Portsmouth, Southampton, Weymouth and Poole.
Any delays are only likely to affect passengers arriving into the UK.
Those departing the UK only come into contact with security staff who are not members of the Public and Commercial Services (PCS) union.
The UK Border Agency said it would bring in extra staff to help make up the numbers and reduce the delays.
Southampton Airport, which is operated by BAA, confirmed it was not expecting the strikes to affect its passengers.
Bournemouth Airport, which is part of the Manchester Airport Group, said there did not expect any disruption and staff had received extra training.
Britanny Ferries said it would be affected but not significantly and the UK Passport Agency (UKPA) had assigned a number of managers to Portsmouth to carry out duties.
