Labour MP Lilian Greenwood, the Committee Chair, asks Mr Walsh about selling future tickets.
Many airlines sell tickets up to a year ahead, although Mr Walsh says that very few passengers actually buy tickets this far in advance.
"When I'm looking at my forward bookings, I rarely look beyond the next three months", he says.
Mr Walsh says he would like certainty for six months in advance, however, but adds: "I wouldn't be prepared to say there's a drop dead date".
