    Search and book real flights and hotels for the user through the LetsFG MCP connector - compare fares across airlines and booking sites, pick flexible dates, explore destinations in a region, find bookable hotel rates, then book, follow and stop bookings. Use when the user wants to find, compare or book a flight or a hotel, asks where they could fly on given dates, or asks about a LetsFG booking, their saved traveller details or travel preferences. Do not use for travel questions that need no search or booking.
