Or even using the Flightline 730/731 service from Basingstoke to Heathrow, bit of a longer journey by bus but will be cheaper than RailAir (especially as only £4 each way under the current £2 single scheme)For Heathrow, I'd consider the Southampton to Woking then RailAir (change at Basingstoke) the best route, depending on the connection at Basingstoke you could also maybe consider XC Southampton to Reading and Rail Air to Heathrow that way (probably more expensive, but less changes).
I can't say much on Gatwick as I've never been so I'll leave it to others.
