* Why she wants to work in the travel industry (saying she loves holidays etc just won't cut it)
* What she feels she can offer the company
* Where she see's herself within the travel industry in 5/10 years time
* What attracted her to the travel industry
* Where has she been on holiday(s)
* Any overseas experience? (she can always tell a small fib there and say she's been a camp councellor with one of these Camp America type programmes, I done it at 18 and loved it and by saying I've done that (truthfully I have) it's opened lots of other doors for me.
* How she might cope if a client is asking hard/strange questions about a destination she knows nothing about
* Flexibility with working hours (most travel agents are open Saturdays and bank holidays etc now)
* Confidence levels with computer based work, what packages was she familliar with (check in staff with say British Airways use a programme called Galelio, it's their reservations system, she could always say although she's had no reservation experience she's aware of the systems that are used in the industry, such as Galelio and is thus familliar with the way in which they do work - that's things like the way names etc are imputted into the system, i.e. /Mr/Jones/Christopher type thing or abbreviations used, i.e. PAX for people or PP/PR/PN for per person, per room, per night, then the obvious ones like SC for self catering etc.
Make sure she's been online, researched First Choice, researched the job she's going for, what it entails, what she might think the pro's and con's are to the job. They always ask for things like "what are your strengths and weaknesses" and it's easy to say "I'm good at xxx" or I feel I have a real talent dealing with xxx type thing so try to think up a weakness that can be turned around into a positive, i.e. "I'd say a weakness is my intollerance to people who say they will do something then don't which in turn looks bad on me but I'm overcoming this by finding more and more ways in which I can better organise myself.
Best of luck to her, I can't think of anything else just now.
