Uk entry with one way ticket
My husband and I want to spend 2-3 months travelling Europe in May this year, then onto the USA to visit our daughter. To date we have only booked a one-way ticket from Australia to London and someone has mentioned to us that we may not be allowed entry into the UK with just a one way ticket... i cant seem to find any specific advice on this subject on various websites, does anyone know if this could become an issue?
We do not have a return date in mind, trying to leave this open so we can be flexible. Our thoughts are at the moment to travel to Spain and setup base somewhere like Barcelona and do various short trips from there.
