As an example, I found seats departing MCO on Wednesday, September 11, returning from LHR on Friday, September 20, 2019.
Tickets at this price point can be found from mid-August through mid-September with returns available through the end of the month.
Departures from MCO are valid Sunday through Wednesday, returns from LHR are available Tuesday through Friday. A Saturday night stay is required.
This international Basic Economy fare only includes one small personal item and a full-size carry-on bag. Checked bag fees start at $60 each way.
Seats will be assigned at random upon check-in for this price. You may pay a fee (for each flight leg) to choose specific seats.
For an additional $140 roundtrip, you can purchase a standard Economy fare, which includes standard advanced seat selection, one piece of checked luggage, and allows ticket changes/upgrades for a fee.
Beware of itineraries with long layovers or those that require an airport change.
Nonstop flights to London-Gatwick from Orlando are available for $342 roundtrip on Virgin Atlantic, but only on a few days departing in early August, returning in late August and early September.
