The rationale for travelling business class is because they have to hit the ground running when they arrive. You'd have to wonder then how those who cashed in their sleepers for buckets coped, although the New Zealand First MP Fletcher Tabuteau arrived before the others, sending a Facebook picture of he and his wife in the hellhole of Paris.
In reality these trips are more about clinking cocktail glasses and socialising rather than slogging.
And if you needed any proof of that, think about former MP Hone Harawira's casual approach to one of the European junkets fostering those closer relations, not with other MPs but with his missus. He went awol, skipping a meeting in Brussels to take his wife to Paris because they hadn't been before.

Some previous travellers on the taxpayer carpet have even indicated they were about to retire, while some of the parties see it as a consolation prize for demotion.
Surely that's one of the reasons why the Nats are sending the likes of Maurice Williamson on the current one.
One trenchant critic of the trips is Act's David Seymour, who says they're a waste of money and reckons MPs earn enough to travel on their own account. He's putting his money where his mouth is by going to two international public policy conferences on his own tab. Obviously he knows how to have a good time.
But methinks he doth protest too much anyway. Being a party of one, chances of him getting on the Speaker's junket are remote, and given his criticism, the odds just reduced even more.
