Thanks so much for all the great info! It has been very helpful

One other question.. a friend of mine mentioned that some of these LCC have baggage restrictions. Restrictions that are so heavy that sometimes it's cheaper to by a seat next to you and strap your luggage in there. Is this correct? I'm not that familiar with LCC in Europe and want to make sure that I don't want make my aunt pay through the nose just for her luggage.

Much thanks...
