Admittedly an increase of 13% on capacity does not sound much but you have to bear (excuse the pun) in mind that the current IPF can only accomodate 900,000 pax per annum, and that the actual facility is very small, therefore you don't want 4 757 plane loads at check in. However CVT has no problems accomodating the 737-300, before BOH opened as a Tfly base, CVT had the two based a/c there and were using them for revenue flights...furthermore there have been several a/c swaps over winter with CVT, BOH and DSA. The 737-800 on the other hand is a very different kettle of fish in relation to its performance at CVT.
