British travellers heading to the US have been warned they could be caught up in travel chaos on Wednesday as two of the country's biggest mobile providers switch to 5G.
Bosses of the top American airlines have written to the White House about their concerns, and fear planes could be grounded and routes cancelled due to the roll out.
Mobile internet providers Verizon and AT&T are switching to 5G but the airlines are concerned they will use a similar wavelength to vital instruments used on their planes and they could interfere with each other.
