One booking vs two: the practical differences
| One booking | Separate tickets | |
|---|---|---|
| Missed connection | Airline rebooks you | May not be protected — a new ticket may be needed |
| Baggage | Normally checked through (official policy) | Collect and re-check, unless through-checking confirmed |
| Process at CDG | Stay in the transit area when eligible | Usually the full arrivals and departures process |
| Border control | Only for Schengen crossings | Entering France applies once you go landside |
Why baggage decides your route
With separate tickets, your first airline’s responsibility ends at CDG. Some airline partnerships can still send your bag across tickets — oneworld and similar arrangements have real cases. But the default, confirmed by airline policy, is: the bag is not checked through unless it was explicitly arranged.
Check your baggage tag at the airport where your trip starts. If the tag shows only “CDG”, your bag will stop there — confirm directly with airline staff if you were told otherwise.
Protection is the other half
On one booking, a late arrival means the airline re-books you (within its own rules — fare class and voluntariness matter). On separate tickets there is usually no such duty, even between partner airlines — the applicable airline’s terms decide. That difference is why the same 90-minute connection can be reasonable on one ticket and risky on two.
What to do before you fly
- Ask your first airline, at check-in, whether they can send your bag to your final destination. Get the answer before the bag disappears.
- Check in online for the second flight and note when its bag check closes — it is usually earlier than the gate closing time.
- Screenshot both terminals and the transfer route between them from this site.
- Know the visa situation: leaving the transit area at CDG is entering France, whatever your tickets say.
