I have noticed numerous companies trying to claw back some of their losses. We went to a restaurant for the first time a couple of weeks ago. The prices were riduclous, service slow and food very average. This kind of action will start pushing at inflation.
LHR are probably saying that it is to encourage people to use public transport. A week ago I took my partner's daughter and son in law to T5 to visit his parents in Madrid. They could have taken a taxi (some 30 miles), a taxi, a train and then a coach or other permutations. They would have difficulty doing that for an 05:30 check in! Even if it had not been the case that she is four months pregnant.
So many companies have such high levels of debt and shareholders demanding returns. But this is what a financial crisis looks like.
