Although the restriction on flights into and out of the UK has been lifted, the closure of UK airspace and airspace in parts of Europe since Thursday 15th April, is continuing to affect our distribution of mail by air. This has impacted on some UK domestic mail which travels by air, as well as mail due to either leave or enter the country via UK airports.
The normal domestic airmail network is expected to operate tonight.
At the moment our contingency plans are still in place to keep as much mail moving as possible, using alternative road and rail networks to replace air services; there may be a small delay to mail being delivered in some areas, until such time as the air network is back up and running as normal"
About Air Mail to the US;
"Airmail items posted 15th-17th April inclusive and addressed to the USA are with airline handlers ready for despatch as soon as flights have capacity.
Airmail items posted from today, 21st April, onwards will be despatched by air with the first flights out of the UK expected to commence this weekend due to capacity constraints.
From today, mail will be despatched in sequential order, therefore some items mail incur a slight delay whilst schedules and airline capacity return to normal."
