1. Probably a Charter or Ryanair type set up.
Luggage weight/number restrictions apply to carrier
2. Either
3. Just under 3 hours
4. Included if taking Cunard price offer. Not included if booking own flight.
Forget this potential mayhem, fly scheduled from Heathrow.
One can book scheduled airline of one’s choice and flight time via Cunard, also upgrade for additional luggage and select seats.
Forget Cunard transfers as they are by large coach, which waits arrivals for other flights to fill the coach before departing (time wasted standing around doing nothing). Book luxury private timed transfers with RomeCabs, price is about £140, not much more than a two person Cunard communal coach tour.
If staying overnight pre-flight, then use Airportr to collect and check in all one’s luggage from the hotel. Then one goes directly from hotel to Security. No searching for luggage trolley, plus missing out on those wonderful check in luggage queues and the shuffle stop routine.
Additional
Pay for the flight immediately, as this will get one the locator reference early, so one can then select seats when the flight opens months in advance, not having to wait until balance has been paid. Better seats go early.
