What are the benefits of the different airports in London and Iasi?

The main benefits of one London airport over another are that only Luton Airport offers direct flights from London to Iasi, as mentioned, and also where the two airports are located. With Heathrow being on the western outskirts of London and Luton being some 33 miles to the north, it might be easier for you to get to one or the other. They both serve return and one-way flights from London to Iasi and have very good facilities for passengers with limited mobility and hidden disabilities, and families travelling with children. Heathrow has the larger children’s play facility of the two, and a more expansive duty-free section, but they both have plenty of restaurants, coffee shops, pubs and takeaway outlets. Iasi is a substantially smaller airport. It has car rental kiosks, cash machines and a Mother and Child Room, plus a snack bar. You’ll also find a small duty-free area.
