I'm booked on the Tuscany trip that will return to UK on 18th Oct. The flight is due in at 4pm.

I haven't been through Gatwick for years and imagine it's far busier theses days. I'll have to get a National Express bus home.

Do you think that 90 minutes would be enough time to get through baggage collection and on to the bus?

I use Gatwick fairly frequently, Usually the North Terminal. I do not usually have a problem but to be on the safe side I would allow 2 hours. This should allow you time to get your National Express tickets and find your Bus Stop. If you are arriving at the South Terminal the bus stops are about a five minute walk away. North Terminal not so far.

Security was the slowest part but my luggage arrived on carousel as soon as i got through, perfect timing.

90 minutes will be fine unless flight is delayed.
