Couples separated by border closures said they feel 'very forgotten' by the UK government's green list for travel.
The newly announced list will allow people to travel to countries including Portugal and Gibraltar from May 17 without needing to self isolate on their return to England.
However, couples with partners who do not live in qualifying countries face expensive quarantine requirements, or an even longer wait to see each other.
They called on the Government to exempt them and others in their situation from the quarantine rules.
Alyssa Pallotti, from Texas, has been separated from her partner, Jacob Greenwood, who lives in Bracknell, Berkshire.
She said: 'I've heard the UK government talking about holidays, holidays, holidays when it comes to this green list, and we feel very forgotten.'
And Garrett Leibovitz, 21, from the US, said he feels 'completely depressed' at not having seen his fiancee, Vanessa Torres Gonzales, 24, who lives in London, for the last 15 months.

'We are actually classed as leisure travel - like seeing your partner is not considered essential. In the US or UK, it is considered a luxury.'
Ms Pallotti said she feels 'very lucky' she has been able to travel to the UK a couple of times since August last year, balancing working her job remotely, but quarantining each time has cost her thousands of dollars.
In March, she spent two weeks quarantining so she could spend four days with her partner over Easter, before flying back to America.
'It's very draining for me because it is just all on me to go over there because he is not allowed to come to the US,' she said.
She said Mr Greenwood would be able to enter the US if they were married: 'But we don't want to be forced to get married just because that is what the government says.'
Love Is Not Tourism, a campaign fighting to reunite families who have been separated by travel bans and border closures, connected Ms Pallotti with other people in her situation.

She said: 'There was a rumour this morning that the UK would be lifting the ban, and that was probably the most hopeful I have seen everyone.
'But now we all just feel very upset and very deflated.'
Ms Gonzales, who is Italian and currently living in London, plans to move to the US once her visa is approved, a process that has been delayed due to the pandemic.
Mr Leibovitz, from Kansas in the United States, said the 'hardest thing' was not having a date to be able to plan around.
He said: 'People on Twitter, act like we are selfish for wanting to travel. But it has been 15 months, and multiple countries have made exemptions for couples, and I don't see why the UK and US can't do that either.
'It's not about holidays, it is about reconnecting families.'
