However, the EU has now said that UK Lorries and flights can operate in the EU and there are moves to extend these no-deal plans further, so now i think we could leave on no-deal, i don't believe the likes of Soubry or Grieve will wreck their careers to save the UK.
Bear in mind these are unilateral arrangements. The EU's doing stuff to help itself, which also by fortunate coincidence helps us too. But they're not "deals" in the sense that they're not things the EU and the UK sat down and negotiated together, and agreed on.
It's like a friend offering you a lift to work because he happened to drive past you as you were walking. You can't assume that creates an ongoing obligation to give you lifts.
Similarly, the EU's temporary fixes are very temporary (until the end of 2019 at the latest) so they don't really fix any of the problems. They can also be withdrawn by the EU at any time without notice (because they're not legally binding deals between two parties).
Finally, they don't replicate the status quo. Both the haulage arrangements and the flight arrangements come with severe limitations that we don't suffer at present.
For instance, in the case of flights, they're based on historic flight routes and numbers of landings/takeoffs, meaning that airlines that have recently expanded their routes will have to chop some of their services to meet the quotas of flights allowed under the temporary fix.
Similarly, in the case of haulage, UK companies will be able to transport loads directly to/from EU countries, but they will no longer be able to take jobs involving transport within a single EU country (e.g. a load from one part of France to another part of France), nor between two EU countries (e.g. a load from Belgium to Poland). So that severely limits their options when it comes to putting together a profitable itinerary of work for any given haulier.
