Package Holiday Price Comparison - TUI, DERTOUR, weg.de

Unofficial, independent price-monitoring tool. Not affiliated with, endorsed by, or sponsored by TUI, DERTOUR, weg.de, ab-in-den-urlaub.de, alltours, or any other travel provider.

Compare package-holiday prices from five German travel sources in one normalized dataset. Enter a destination, travel window, occupancy, duration, and departure airports to receive hotel + flight offers, same-hotel comparisons, airport matrices, price histories, capacity signals, and transparent buy/wait forecasts.

Why use it?

• Find the cheapest source for the same GIATA hotel with dachEntityId.
• Compare Düsseldorf, Munich, Frankfurt, or other departure airports.
• Build a deduplicated 90-day price curve for each stable package.
• Detect narrowing market availability from repeated observations.
• Create explainable buy/wait signals from price trend, volatility, days to departure, and availability evidence.
• Send optional signed webhook alerts with cooldown and retry protection.
• Keep partial results when one source is temporarily unavailable.

The Actor is built for tour-operator pricing teams, OTAs, travel agencies, and travel-market analysts. It collects observations, not bookings. A provider may revalidate price or availability at checkout.

Quick start

Use this minimum input:

{
  "destination": "Antalya",
  "startDate": "8 weeks",
  "endDate": "10 weeks",
  "nights": 7,
  "adults": 2,
  "childAges": [],
  "departureAirports": ["DUS", "MUC"],
  "operators": ["tui", "dertour", "weg", "aidu", "alltours"],
  "outputMode": "comparisons",
  "maxResultsPerOperator": 20
}

Dates accept either an absolute YYYY-MM-DD value or a rolling relative value such as 8 weeks. The Store form is prefilled with a valid rolling window so a new user can run the example without repairing stale calendar dates.

Results are written to the default dataset. OUTPUT in the default key-value store contains run status, record counts, source health, quality indicators, errors, feature summaries, cost telemetry, and billing operations.

Live sources and evidence

Source	Transport	Hotel identity	Notable evidence
TUI Germany	Direct JSON	GIATA	Price, date, duration, room, board, discount
DERTOUR Germany	Direct JSON	GIATA	Flight legs, transfer, availability, flex marker
weg.de	Browser + intercepted JSON	GIATA	Flight, transfer, deal/flex markers, old price
ab-in-den-urlaub.de	Direct JSON	GIATA	Price, room/board, flex text; cashback is separate
alltours	Persisted GraphQL	GIATA	Flight, package operator, free cancellation, old price

Missing flight, baggage, transfer, cancellation, tax, or fee data remains explicit. The Actor does not invent unavailable fields. Optional, bounded weg.de detail enrichment can fill evidence-backed baggage, transfer, and flexible-cancellation fields and uses a persistent positive/negative TTL cache.

Comparison modes

• lowest_offer_in_search_window compares the cheapest hotel offer returned by every selected source.
• like_for_like_package additionally matches departure date, nights, occupancy, airport, normalized room class, and normalized board class.

Match-quality fields label exact, normalized, requested, mixed, and missing dimensions so downstream systems can decide what is comparable.

Dataset record types

• offer
• comparison
• airport_matrix
• price_series
• market_signal
• buy_wait_forecast
• alert_delivery
• run_diagnostic - emitted without a result charge when no primary rows can be written, so an empty search, partial source outage, and spending limit are immediately distinguishable.

Real records from live runs

The two records below are unedited engine output from live runs on 2026-07-28; only image lists and one very long source ID are shortened.

A real cross-operator comparison: the same GIATA-identified hotel, like-for-like window, three portals, and a real 27 EUR spread. matchQuality declares per dimension what was matched exactly and what was normalized, so a like-for-like claim is auditable instead of asserted:

A full offer record, including both flight legs as sold. Price honesty is structural: originalTotal, savingPercent, and taxesIncluded stay null when the portal does not publish them, and price.completeness says so explicitly. Hotel reputation fields are passed through as the source states them, even when they are unflattering (this 2-star property shows its single review and 0 percent recommendation as-is):

The full input is in examples/INPUT.json, a recurring watch is in examples/SCHEDULED_WATCH.json, and a normalized output sample is in examples/OUTPUT_OFFER.json.

Reliability and limits

• Each source has typed errors, bounded retries, health summaries, and circuit breaking.
• Airport matrix fan-out has explicit airport, concurrency, and request limits.
• Explicit source-airport fallbacks are discarded when they do not match any requested IATA code, and the mismatch is reported in run diagnostics.
• Price history is sharded, deduplicated, retained for 90 days by default, and stable across transient offer or flight identifiers.
• Capacity scoring requires repeated observations and is suppressed when source coverage drops. It estimates market availability, not hotel occupancy.
• Forecasts are informational signals, not price or booking guarantees.
• HTTPS webhooks support HMAC signatures, idempotency keys, cooldowns, bounded retries, redirect blocking, and target-URL redaction.
• alertSigningSecret is a top-level encrypted input and is mapped into the webhook runtime configuration without being emitted.
• Pay-per-event guardrails stop work and output before the caller's maximum charge is exceeded.

The Store input defaults to one stable German residential Apify Proxy session because several sources bind browser cookies, CSRF tokens, or availability to one network identity. Browser-backed fallbacks activate only when a direct source response is blocked or empty. Source APIs and persisted-query hashes can change; source-specific schema drift is reported without discarding successful sources.

Pricing

This Actor uses pay per event. The primary event is one normalized package offer. Separate named events transparently account for successful source searches and optional comparisons, history, matrices, signals, forecasts, enrichment, and alert delivery. Failed source searches, failed webhooks, cooldown-suppressed alerts, and duplicate history observations are not charged as successful events.

The Store headline shows the primary package-offer price; a five-source run can also charge up to five successful-source-search events. Review the full Pricing tab, set a maximum cost per run, and inspect OUTPUT.billing before increasing result or airport-matrix limits. Platform usage is currently included in the Store price, as shown on the public Pricing tab.

This Actor is also exposed to AI agents through Apify's MCP server (mcp.apify.com): an agent can discover it by search and run it with the same pay-per-event billing, with no separate integration.

Privacy and lawful use

The Actor does not require traveller names, email addresses, payment details, or booking personal data. Child ages are optional search parameters. Webhook URLs and signing secrets remain within the caller's input and storage.

Users are responsible for lawful, proportionate use and compliance with applicable website terms, robots policies, database rights, privacy law, and contractual restrictions. Do not use the Actor to bypass access controls or overload source systems.

Support and versioning

For reproducible schema drift or source failures, include the run ID, redacted input, affected source, and first error code. Target initial response is within two business days. Upstream website changes are supported on a best-effort basis unless a separate SLA exists.

Breaking output changes use a major version; additive fields use a minor version; source fixes use a patch version. See CHANGELOG.md for release history.

Local development

Node.js 22.19 or newer is required.

npm install
npm run release:preflight
npm run release:live

For a local Apify run, place input at storage/key_value_stores/default/INPUT.json, then run:

$CRAWLEE_STORAGE_DIR="$PWD/storage" npm start
