How safe is it to travel in early pregnancy ?

We were ttc baby no 2 and we have just found out that we will have to relocate due to my husbands work. If the relocation happens it will happen in August and will involve at 14 hour long flight and a total travel for around 20ish hours. Just not sure how safe is it to travel in early pregnancy if we happen to conceive.

Should we still continue or wait till we have relocated ? Sorry might sound a stupid question to some but I’m very confused as I really want a second one as my first one is already past 4 now and I will be turning 34 this year. Thanks.
