Set up deal alerts that you can actually judge
Use 1,037 dated city-fare observations to choose destinations and practical departure airports for your alerts. Compare each alert with your actual dates, baggage needs and acceptable journey.

Not listed? We price 26 gateway metros. Pick the one you would drive to; the plan then tells you whether a second airport belongs in the alert.
Pick your airport and the plan appears here: what counts as a deal from there, who sells it, and how to set the alert.
Choose the trip before the threshold
Start with your departure airport, destination and dates. Decide which connections, arrival times and ticket restrictions you would accept. A fare below a historical floor can still be a poor purchase if it adds an overnight stop or omits bags you need. For a flexible trip, use the city results to decide what to search next.
How to read the results
Your airport. The gateway median summarizes its observed destination floors. The carrier list records which airlines returned accepted quotes in a separate fixed-week search. Neither measure explains why airlines set their prices or predicts how often an alert will arrive.
Alert lines. The displayed thresholds use the same editorial bands as the Fare Deal Checker: 5% and 15% below the recorded floor. They flag an offer to investigate; they do not establish a normal price or tell you whether waiting will save money. A business-to-economy ratio can involve different airlines, routings and observation dates, so it is not a same-flight upgrade price.
Other airports. Nearby candidates use a 300-mile screening radius and a $100 gateway-median difference. A more distant gateway can appear at a difference of $200. Different route samples can create that gap. Confirm a matched current quote and add bags, ground travel, parking, lodging and time before deciding whether to drive or position. The Alternate Airport Checker helps identify candidates.
What a green airline means
Green marks a median economy premium of $25 or less over the observed route floor on that airline’s own sample. It does not mean the airline was cheapest on every route, or that its fare included the same bags and schedule as a rival. Search the named airport pair before choosing an airline.
Set alerts with the right coverage
Google Flights provides free tracking for specific Europe searches. Going’s free plan covers select continental-US economy deals; Premium includes international economy alerts and Elite adds premium cabins. Choose a service for the coverage you need. An alert is a prompt to compare the complete offer, not evidence that a historical fare remains available.
Keep the dates attached
The city grid was observed over its disclosed collection interval, for departures in August 30, 2026 – February 28, 2027. The carrier grid uses its own fixed travel week and dates. Neither sample establishes seasonal pricing, future availability or how often fares fall. The data page keeps the methods and current coverage together.
Common questions
- How do I set up flight deal alerts to Europe?
- Set your departure airport and European destinations, then check the service's coverage. Google Flights offers free price tracking. Going's free plan covers select continental-US economy deals; its Europe economy alerts require Premium or Elite. The wizard gives you historical fare comparisons from your airport to help evaluate an alert, alongside its dates, bags, routing and ticket rules.
- What price should I set a flight alert for to Europe?
- Choose a reference for your airport and destination, then compare the complete current ticket. The cheapest New York–Reykjavik week in our dated city sample was $422. The wizard marks $400 and $358 as editorial alert thresholds, 5% and 15% below that historical floor. These are screening choices, not normal market prices, live offers or booking deadlines.
- Should I add more than one home airport to my alerts?
- Add airports you can realistically reach, then compare the same destination and dates with all transport and ticket costs included. The wizard screens nearby candidates within about 300 miles using a historical gateway-median difference of $100; 4 of 26 gateways meet that screen. Those medians cover different destination samples and do not establish a saving on your trip. New York is one candidate shown for Philadelphia.
- Are the fares in the wizard live prices?
- No. The city sample contains 1,037 historical round trips observed August 30, 2026, with departures in the August 30, 2026 – February 28, 2027 window. Each value is a flexible-date floor, not a current bookable offer. Business comparisons use a separate fixed-week carrier sample with its own dates and incomplete-coverage disclosure.
- Is Going Premium worth it, or is the free tier enough?
- Going's free plan covers select economy deals within the continental US, so it does not cover this site's Europe searches. Premium includes international economy alerts; Elite adds premium economy, business and first class deals. Whether a paid plan is worthwhile depends on how often you travel and can use its alerts.
