Apologies if this is covered, I believe I know the answer but wanted to double check.

I want to book return flights LGW-MCO, departing on 20 May 2020 and returning 2 weeks later. At present, the outbound flight is the only on available online, and the return should be available in just under 2 weeks time. Is this going to be the same if I phone reservations, or will they be able to offer a price for the return journey.

I anticipate that I will have to wait another 12 days however I intend on booking, but had seen that some airlines are able to offer some sort of placeholder booking price for return flights that went over this period where the return flight was not on sale yet.

Thanks in advance.
