Given a travel related situation, and given a specific question about the situation, summarize the question into a title

[EX Q]: (applies to all travel agents, I'm just using FC as an example)

Flight Centre - the world wide travel agent, often boasts "lowest prices guaranteed". I've had trouble getting them to actually hold to this in the past, but generally if you can prove you can get the price elsewhere, like a print out of say, AirNZ's website with a price, they'll match or beat it.

Does anyone know if they'd be willing or able to match ITA's Matrix site? It gives prices, but doesn't always indicate WHERE those prices are available. If you took those prices and flight details along to a travel agent, like Flight Centre, are they able to find the flights for the same price, given all the flight details, assuming the flight is actually still available?

[EX A]: Travel agents - can they match ITA Travel Matrix prices?

[EX Q]: Starting from Paris, I want to make a one-day trip combining a visit the Bayeux tapestry museum and with a tour of some of the D-Day beaches. How can I travel between Paris, Bayeux and the beaches? Which beaches would I have time to visit?

[EX A]: Bayeux tapestry and D-Day beaches

[EX Q]: I am planning to book a direct sleeper train from Innsbruck to Prague through Ceske Drahy/Czech Railways. The train page says:

Depart from Innsbruck Hbf
(Train name: EN 467 EN Night Jet /EN 463/S 1540) to Praha hl.

Why are there so many names of this train or am I wrong to assume that this is a direct train? The train name changes from Salzburg Hbf (dep. 3:50) to train no. EN 463 and from station Linz Hbf (dep. 6:35) to Train S 1540.

Does this mean I would be required to change trains at Salzburg and at Linz?

[EX A]:
Is the Innsbruck to Prague sleeper train really direct?
