At the present time there are no particular announcements of significant fleet expansion or reductions. The economic situation with regard to cost pressures (fuel costs, taxes, credit availability ) are well publicised and likely to result in most carriers consolodating their existing positions.
Most recruiting for this summer season is probably complete. However there is always a small amount of movement caused by people leaving to join other companies, long term sickness and retirements. The latter is normally anticipated in the previous winters recruitment numbers, and the former are to some extent also "guesstimated" into that recruitment drive. However any unforseen or unexpected change in the numbers might generate a need for additional numbers this late in the training cycle. It certainly wouldn't be the first time that has happened.
In this industry events can quickly reshape future plans, but the near to mid term outlook given the current status quo is probably small scale recruitment in line with current market projections over the next 12 to 24 months.
