We're planning our trip over to see MIL which involves an international flight then a domestic flight via Istanbul. I would like to stay at a nearby airport hotel overnight without having to take all our luggage out with us. We've done this in the past and just used our hand luggage for overnights bits as the flight times worked out that we'd be sleeping overnight in the hotel otherwise. This time the flights fall too close together to justify staying in a hotel so my question is, can a travel agent arrange flights classed as one ongoing journey even if it's not a journey offered on the likes of sky scanner etc? For example, I'd like the 10:40am flight from the UK then a 5:30am domestic flight the following morning so we have a decent amount of time in the airport hotel. Is this possible if there's an option of a 10pm same day domestic flight so essentially getting you there quicker but not what we want.
I hope this makes sense! I know we could just do two bookings and take our luggage with us but we will have so much with car seats and the cases that it would be a right faff.
