It could force families to shell out hundreds of pounds on tests so their children can come with them.
Children aged 12-15 are also only eligible for one dose in the UK, and so don’t count as fully vaccinated.
France’s vaccine passport is already mandatory for bars, restaurants, and entertainment venues, but will be extended to ski lifts, ministers announced yesterday.
In order to qualify for the same rights as an NHS Covid pass holder, many single-dosed children would need to take a PCR or antigen test.
One school trip travel provider has already cancelled trips for 2,000 schoolchildren to Italy and Austria over similar rules.

Dr Olivier Véran, the French health minister, also announced that booster doses would be available to everyone over the age of 18, five months after their second shot.
