Should we book one-way or roundtrip tickets?

Roundtrip is almost always cheaper for Europe from the US. One-way only makes sense if you're unsure about return dates or planning to travel elsewhere after Europe. Price difference can be $300+ per person.

Is it cheaper to book flights separately for each city?

Not usually. Multi-city tickets through one airline cost $100-200 more total but save time and hassle. Separate bookings risk missing connections if first flight delays, and you lose protection between different airlines.

When should we absolutely not travel to Europe as a couple?

Avoid July-August (crowds, heat, high prices) and December 20-January 2 (expensive, cold, many attractions closed). Late June and early September offer better weather with fewer crowds and better prices.

Should we pay extra for seat selection?

Yes, especially for couples. Airlines don't guarantee you'll sit together even when booking simultaneously. Spend the $50-150 total to choose seats together, preferably aisle/window pair or two aisles across from each other.

How to Book Flights for a Couples Trip to Europe

Book European couple flights 2-3 months ahead for best prices. Use Google Flights to compare, consider multi-city tickets for 2+ destinations, and book both passengers together to guarantee seats side by side. Expect $600-1200 per person from the US depending on season and destination.

Choose your European destinations first. Decide on 1-3 cities maximum. More destinations mean higher flight costs and rushed itineraries. Popular couples routes: London-Paris, Rome-Barcelona, or Amsterdam-Prague. Multi-city tickets work best for 2+ destinations within 1000 miles of each other.
Set your travel dates with flexibility. Pick your ideal dates but stay flexible by 3-5 days. Use Google Flights calendar view to see price differences. Avoid July-August and Christmas week when prices peak. Best deals: late September-October and January-March (excluding holidays).
Search flights together, not separately. Always search for 2 passengers at once. Airlines show different prices for single vs. couple bookings. Use Google Flights first for overview, then book directly with airline or through trusted sites like Expedia for customer service.
Compare departure airports if you have options. Check all airports within 2 hours of home. Price differences can be $200+ per person. From NYC area: JFK usually cheapest to Europe, but check Newark and LGA. Los Angeles often cheaper than LAX from Burbank or Long Beach.
Book both passengers simultaneously. Never book one ticket then try to add the second later. Airlines don't guarantee you'll sit together. Book both at the same time, select seats immediately (pay the fee if needed), and confirm you're traveling together in booking notes.
Add essential protections. Buy travel insurance within 24 hours of booking for best coverage. Get airline insurance for trip delays/cancellations (usually $50-100 total). Consider upgrading one or both seats to premium economy for long flights - the comfort difference matters for couples.
