#normalization

Diagnose hotel tax and fee differences through explicit base/total semantics, currency handling, occupancy and market context.

Normalize fare families, baggage allowances and ancillaries from airline/GDS/NDC sources into a canonical flight-offer model.

Design hotel search across multiple suppliers using fan-out, normalization, deduplication, timeout budgets, partial results and ranking.

Isolate hotel and flight provider contracts behind adapters with explicit DTO boundaries, normalization, error taxonomy and versioning.

Learn how to normalize room types, rate plans, occupancy, meal, cancellation and package metadata so hotel offers can be compared without hiding meaningful differences.
