Hey a.netters, I'm sure this has come up many times, but I can never seem to locate adequate threads. They are either outdated or simply too general. Anyways, here is the situation: My mother will be traveling from MCO-LGW and then from LHR-BEY on Virgin and BMI, respectively. The flights are booked under the same ticket. She has around a 12 hour wait in London, so time-wise, I'm sure she will be fine. I have never transfered from Gatwick to Heathrow before since I usually fly straight into LHR by connecting via IAD or ORD or some other airport that flies straight into LHR. I rather make an extra stop and not have to transfer. My mother wanted to reduce the amount of stops, so the only adequate flights were through London or FRA. Flying into FRA was almost triple the cost of London, so it didn't make any sense to fly into FRA.
My question is: What is the best and safest way for my mother, who is traveling alone, to transit from LGW to LHR? Also, please tell me specifics, like timings and lengths, etc.
Thanks for your help!
