Review of most airline Y flights: OK for the price; or avoid if possible.
Review of most 3 star hotels: small rooms but value for money; or stay elsewhere.
Business Traveller (the magazine) used to put out annual first, business and economy comparisons... listing the seat pitch, width, recline, WC-to-pax ratio and cabin crew-to-pax ratio. (The really old versions used to include whether in-seat screens were available!)
There’s still a market for something like that today, which could be extended to include whether or not an airline has paid exit seats, overhead air vents, and whether their 777s are 3-3-3 or 3-4-3. And perhaps whether meals are fully catered or buy on board (like
Etihad). BT used to send out a request to airlines and compile the results.
For hotels there can be some good deals out there like... a couple of years ago there was some deal to get a bonus 2000 avios per stay at hiltons. Or with accor you got double then triple accor points for one, two or more stays. Those can sometimes get missed.
There could be reviews on the Hub Premier Inn hotels, and MotelOne (both which take the easyhotel concept, but make the rooms deluxe). These can represent significant savings over premium properties, or be of much better standard than easyhotel.
There’s lots and lots of real information, that can save businesses money, and make for a better journey. But this really needs people who have the real-life experience and knowledge to bring these stories.
