When this route gets cheap.
The cheapest itinerary we are tracking makes 2 stops and takes about 14 hours outbound, on a 20-night trip — ticketed under Frontier Airlines, which on a connecting fare need not operate every leg. At $1,433 for 8,778 km each way, that works out to about $82 per 1,000 km flown. That is above the $44 per 1,000 km typical of long-haul fares here. Across the 18 departure cities we track at a similar distance from Prague, this fare ranks 18th — 2.9× the $490 we hold from Los Angeles. For context, the middle fare among the 31 routes of similar length we watch out of Houston is $833. We have 1 month of cached prices for this route so far — not enough to call a fare cheap or expensive, so we publish the price without a percentage. Fare history here is still too short to name a cheap season. The best time to be in Prague: Apr–Jun · Sep–Oct.

Good to know
HOU → PRG, answered.
How far in advance should I book HOU → Prague?
We do not publish a number for this, because we cannot measure it yet. Answering it honestly means watching the same departure date on this route over many weeks as it approaches, and that archive is still filling up — so any "book N days ahead" figure here would be borrowed from somewhere else rather than measured. Our guide Why flight prices change covers the levers we can measure.
Are there nonstop flights from Houston to Prague?
The current cheapest fares involve a connection, ticketed under Frontier Airlines. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on 17 October). Airlines reprice constantly, so the booking search re-checks the live price before you pay. Fresher finds are far more likely to still be available.
